roll bar holes

[wachterg]

anyone no where there is a drawing for drilling holes for roll bar on ac cobra

This will get you close. Note the left brace is generally in line with the rear trunk line. The front braces should be exposed behind the seat, if you can do that with your particular car. make the holes small at first, and then enlarge your holes to fit your bar.

The holes are completely dependent on where the frame mounts are located (or frame members for attaching mounts) which is completely dependent on the manufacturer. In other words, it depends on who made the car and the year it was made.

That's only if you want it to actually do something when you flip the car. A lot of the cars have "cosmetic" roll bars... and I'm thinking of the Contemporary I almost bought a zillion years ago. If you want it to support the car while you're sliding upside down, then you're going to have to take it to the frame, or equally strong supports.

Contemporary was just being realistic in that neither roll bar was actually sufficient by today's standards. No race club will allow you to race with the standard hoop available on any brand replica including Shelby and Kirkham.
They are all just cosmetic rollbars like Contemporary pointed out 25 years ago.

I'm taxing my memory, but I recall discussing this very issue with Peter B. in the early 80's and, as I recall, it was not the mounts but the roll bar itself. I'm pretty darn sure that I was assured at the time that a true, heavy duty steel roll bar could be obtained elsewhere and that it would "do the trick." I think I'm sure of that, but it's going on 30 years now so it's possible I'm wrong.

Yeah, I remember my old Classic Roadster said the same thing. At the time I found that confusing. I always thought it was a "roll" bar, not a "show" bar.

It's a role bar, since it's playing the part of a real one.

[mreid]

Bwahahahahaha!

Hey, at least somebody laughs at your jokes.

[mreid]

As does Kirkham. I also do remember that that Classic Roadster cosmetic bar was little more than bent exhaust tubing. And just to be clear, that was on a Sebring MX, don't know about their cobra.

The CCX roll bars were just too thin on the wall with seamed tubing. Some of them had little or no mounting on the rear brace. The shorties to fit under a hard or soft top weren't tall enough or strong enough to be of any use. They are somewhat akin to the exhaust tubing ornamental roll bars on Jeeps and Pickemups. I know where you can get functional ones for a couple of different breeds. The thread originator (remember him ;-)) didn't tell us what frame it was for did he? Mreid had the skinny for him on it though.

You're right, I bet I don't.

"Cosmetic" is the wrong word. "Ornamental" is more appropriate.
