Rear bulkhead trim

It's interesting how sometimes this stuff does get remade. I have an early Land Rover (well, a '67) which used a particular heavy-duty vinyl in grey with a black grain pattern, known as 'elephant hide'. A specialist trimmer in the UK has started making a new version of this, which is a very good match. Unfortunately it's not cheap (he eventually sold me a roll of 5m for £250), and he's very reluctant to sell it loose at he makes complete trim panels to sell himself. I guess if the market's big enough...

Big point there Roger, "....if the market's big enough....". So far, the market for truly original specification parts and materials for Cobras and 427 Cobras has not been "big enough" to support recreating the small parts and materials Bills Of Materials and trying to sell the parts retail. I understand as a single small run of new parts of most types might take ten years or longer to sell off. Businesses just don't do well with a decade or more long inventory turn overs.

A few us sometimes buy into upcoming runs even if our cars don't require the part right now because if might be decades before somebody makes another run or maybe they won't make a second run. I have no intention of making additional runs of any part that I have ever made or had made with one exception and it only works with original front ball joints.

Yes, there's the rub. We are lucky to have Gerry Hawkridge in the UK who is producing patterns for parts and producing original-spec suspension components and some other items. I don't know how much profit he makes from this but the business does seem to be growing. He's making patterns at the moment for the aluminium water manifold casting, and the header tank aluminium pipe with heater take-off. I have impressed upon him that the manifold needs to have the original boss included so we owners can saw it off, as original. Finishline do a replica piece for this but they have omitted the boss, thereby marking the part out as a replica. They're none of them perfect, but they're trying, can't deny that. Getting a leather grain right is a whole different ball game, though.

I contacted him about one specific assembly that he made exactly like original. He only made a few and won't do it exact again as just like originals it was as fragile as original. What he sells now generally looks the same but has been updated to suit buyers that don't want something as fragile as an original. I don't know about any other of his parts but most of the American makers of parts have also updated designs in part to make them cheaper to make and or more robust. They then are not truly original specification anymore. Most of the new replacement parts I have held are at least 10% by weight heavier than originals as makers produce heavier duty parts for one reason or another. One maker was doing control arms that were twice as heavy as originals.

Yes, the market for true originality is even smaller. Most people want the correct look but 'improved' design if it's possible. I have fitted NOS parts to my car over the years with other folk incredulous that I have actually made the car 'worse' in their eyes. 'Worse', maybe - but more original. Most folk don't understand that mindset. Fair enough to the remanufacturers, I suppose - they won't last long if they ignore the majority of their customers. The agenda is different.

Lots of parts don't make or change the character of a car, the feel that original street and race car builders and users experienced. Using stainless steel trim screws in place of the chrome plated brass ones AC Cars used, no. Replacing dozens of British Grade R hex cap screws and bolts with modern American anything, no. This leather versus that, no. However there are a lot that do. Revised chassis, revised suspensions, different transmissions, stroker engines, and added weight just won't "feel" the same as a new original in 1964 and that’s ignoring radial ply tires which USA cars never got new. (Driving an almost unmolested 1963-64 Cobra (or later 427 Cobra) on modern radial tires? I promise you that the feel is not the same as it was on hard rubber compounds narrow treads bias belted tires in the 1960s. What did that new Cobra road test say back in the day, something like ‘driving a Cobra was like feeding an oily snake to a greased pig’. No, I won’t give up radial tires thank you very much.)

Gentlemen- thank you - Roger, Dan and ACHipo;this gives me the information I need to do the job justice.

Ditto, Lee - probably see you in the next couple of weeks or so anyway through the Cobra Register meetings.

Thank you!

Roger - I'm also looking forward to making my car 'worse' over the coming months and years; just as it would have been in period.

Haha!
Interesting to note the slight raised section of the curtain for the 427's taller transmission tunnel, otherwise looks pretty much the same.

This is a silly question to those in the know, but since I'm not, and should have a body / chassis to start working on next weekend, what is the purpose / function of the step at the bottom of the bulkhead?

Educated guess, a good place to store side windows.

So, there is no functional purpose other than providing a bottom to the bulkhead "box"?

[DanEC]

I'm speculating but I think it boxes in a frame cross member. The two front roll bar feet are secured to something solid under it on the SC cars - has to be the frame.

On a Cobra (leaf spring chassis) you might argue that the little shelf helps hide the nose of the differential but that seems a weak idea. Without the shelf, where would the side windows get stored? In the boot compartment just tossed on top of the spare tire and free to slide around? Behind the seats with just a flat plane bulkhead, then you couldn't get full rear seat position adjustment; which is important to taller occupants.

On a Cobra roll bar hoop legs go through the shelf if a factory style bar is installed “through the body” which was typical. Mounting tabs and sockets for the roll bar hoop legs had to be added to the chassis. However, SAI did install a few “behind the seat” and those installations didn’t require holes in the shelf we are discussing. My red car, at various times in its existence had “behind the seat” and “through the body” roll bar installations. The installation present since at least the last 1970s early 1980s is through the body; which also required rear bulkhead and fuel tank modifications.

I’ll leave 427 Cobra factory roll bar installation comments to somebody else.
