Thank you so much Dominik for the contacts. I’m still unsure in terms of a one off piece of glass production what is needed as a mould. Can a plexiglass be used? Can it be scanned into CAD and the glass be moulded from this. Sorry these questions are not directly to you but to anyone in the automotive glass industry. Thanks again.

When I inquired for my Maserati replica the designer who created the 3D model "spoke" to the manufacturer directly. They were discussing cord lengths and other dimensions. Pilkington (N. Gardiner) actually had Maserati A6 glass, but not from the Berlinetta Coupé.

3D scans are easy and cheap nowadays. Perhaps even people who print in 3D have handheld scanners.

Otherwise, old school, I sent a shaped aluminium sheet to a local manufacturer (in SA).
They create a template on pins, almost like a needle bed, and drop the soft glass onto it.
Youtube should have videos.

A plexi might change shape in transit (open up).

Apologies for the delayed reply Dominik. I didn’t think about 3D scans. Might be possible to have the plexiglass scanned on the car. Interesting how the glass is shaped. You learn something new everyday.

Update. Phoned Uro Glass today the company that made the glass rear screen on the Dax Daytona I saw previously and had a very long chat about the process. They are about 65 miles from me so not too far and very helpful. Basically a 6mm frame is made in the shape of the periphery and the glass is heated to 650 degrees C and gravity is used to form the shape. Mass produced glass is press bent. This seems to be the most expensive bit 4,800 euros (more or less the same as a British pound now). A minimum order of 25 is required unless they put it through as experimental then they might be able to go down to 15. The base price of each unit is about 2,200 euros/pounds. Then there is the cost of the obscuration band which is silk printed which allows bonding to the host car frame. Also a choice of toughened/laminated/heated at more cost. As I suspected the only way to bring the cost down is to increase the numbers which will dramatically reduce the frame cost down but have a much lesser effect on the rest. He also talked about the weight which was interesting. 1mm thick glass weighs 2.5 kg (about 5.5pounds) per square meter (about 10.7 square feet). So 5mm thick glass is 12.5kg per square meter. You can appreciate the weight saving on original racers!
His sales manager is also a petrol head and doesn’t live to far from me so is going to call in to look at the car and rear screen. So as I suspected low volume = increased cost. Don’t know if there would be any interest on your side of the pond to increase numbers? But that would depend on number of SV Daytonas you have. Perhaps I should contact Dana. Anyone any idea of the approximate cost of a plexiglass version to make a comparison.
Merry Christmas (Thanks Giving) to you all!

If I draw a blank with Uro Glass I’ll follow Dominik’s lead with Pilkington. Thanks Dominik.

Good luck! :-)

It's the most tedious part to organise when building a car. You should have one advantage vs a (front) windshield. You don't need to adhere to the legal requirements.

In Johannesburg I paid only ZAR 12.000 (GBP 600) for the mould and R6.000 per windshield. However, I had delamination at 2 of my 3 copies. Which they rectified. This was in 2018 which could be 30% more expensive today.

I recently had a rear screen made out of lexan for my coupe and it was 485 €

[Daytona Dek]

Thanks @Blacklemming, considerably cheaper than glass. Was it an automotive company that supplied it or a lexan company that shaped it? Also how is it fixed to the frame? Riveted?

Hello, I talked with Steve at Pro Curve glass about a windscreen for a Daytona. Follow the link, there is a photo of them working on a FF Daytona rear screen. https://www.procurveglass.com/markets/automotive/

[Brad54]

I could use a windscreen if anyone has a lead on one that is close to the original.

[MAStuart]

Brad What are you building that needs to be close to original? When you talked to Pro Curve did they give you a guesstimate on cost to do a windshield. I have a windshield that is supposed to fit an original car. But the perimeter is not a mirror image side to side. Also the glass surface shape if different side to side. I found this out doing metal work in the windshield area of my scratch build. I think when Kirkham first started building there coupes they were having problems the glass in the windshield area. I think my glass came from the same source as theres did and I think the glass is not consistent from glass to glass.

[Brad54]

Hi Stuart, I am working on a scratch build too, from Chuck Lindquist plans. Kirkham gets glass from Poland from what I have heard. When I talked to Pro Curve they needed a lot of information I didn't have at that time, before I got the first set of plans I was trying to find the glass since I though it would be the most difficult part. Steve would not confirm or deny that they made the glass rear screen for the FF coupe. So I am keeping them in my back pocket in case I have to have a piece made. Chuck said he would add the dimensions from his car to the body plans. I don't think any of the replica companies come close to the originals. I was told that Hawk Cars in the UK can get the Polish windshields, but I have been in contact and they haven't answered that question yet. I also am looking for lower ball joint forgings if anyone has a solution for that problem. Hawk has original design ball joint forgings on their complete "wishbone" for 360 British pounds. Pretty reasonable, but I am waiting on a quote from them on their adjustable set. Let me know how you solve your windshield problem, I would be willing to split the cost of production with some one if we could figure out the process. I did see a thread here about trimming a mid year Ford Falcon windshield, which is a cheap solution but I have not looked into it other than to know they run about $190. So not a big investment.

[MAStuart]

Brad we need to talk some more. My plan # is 141. What is yours? How far along are you on your build? Do you have a link to the falcon windshield cutdown? I think I am going to make the A arm casting or forging out of billet steel like Kirkham is now doing. They might sell a set? I just need to find out what type of steel they need to be made of. I have a set of castings from George Petrus but am not real thrilled with the machining. Tom Petrus has investment casting but said he will only sell complete arms.

[Brad54]

I have set 212, and am working on the ladder frame, have off all next week to work on it. Currently ready to install the A arm supports that I made. I ordered a set of adjustable A arms from Hawk Cars, and from the photo's they look pretty awesome. Chuck told me today that he will offer ball joint plans next month, he is currently about 3/4 the way done. The Falcon info was a thread on the Daytona section of this site. Bruce? who makes fiberglass bodies commented that he uses them. I think he said 4 inches of the top. but I remember for sure it was 4 inches, but maybe off the bottom. If I can get a few measurements from Chuck, I am pretty sure I can find something close in curvature to cut down. I believe standard "sweeps" are used and that would mean something close is out there. There was an episode of "wheeler Dealers in America" where a glass guy cut a Camry windshield to fit an Opel. He said there are only a few shapes out there and its a common thing to do. Check out you tube for more info on how to cut and file the edges. Delaminating could eventually occur but, worth a try. I bought a few things from George and he told me the same thing, only full A arm sets. In the end everyone who is offering them is charging about the same amount of money. Hawk's will be a little more by the time I buy the hiem joints locally. But they look like high quality. I will know in a few weeks when they show up. The non adjustable A arms are 360 pounds or about $478 each plus taxes and lots of shipping.

[Brad54]

Chrome moly should be as strong as a forging, but to double check there is a site that explains the forging process and why its better than cutting from billet on occasion. You could have them hardened but that would require another round of machining due to the process. I have decided to save somewhere else on the project, I was just spinning my wheels only to probably spend more money in the end and end up with something that just sort of works. Its a sensitive location after all. Losing a wheel would not be fun!

It is a company that specialises in all kinds of plastics
Splashscreens,countertops,….
I have bolted it

Thanks for that. What did they use as a template? Bolting is probably better than riveting where you can control the pressure on the plexi.

If you can get your hands on the Cobra Daytona Coupe book , there's a picture of the boys brainstorming the design of the coupe with Ken M sitting in a bare frame, with a Falcon(Sprint?) in the backround. the sprint /hardtop/convertible winshields is what I used when I made the buck/ plug for my body, trimmed off about 4" off the top, maybe some one could send Pete Brock an E-mail and see if they started with a falcon windshield, but i'm sure with FoMoCo's deep pockets ,they could have anything made. I investigated getting new windshields made, but couldnt get a straight answer from anyone, they were thro'n numbers of $25K for the tooling and then a minimum of 100 pieces, i gots holes in my shoes ,too rich for me. Anyway, That is my story on my windshield, but the original thread started about the rear glass, no?

I have a glas screen but prefer not to use it because it screams”kit car”
So they used that as a template.
And want the look to be as period correct as possible.
Bolting indeed is the better option
