[EricTopless68 Camaro]

Okay guys, I have a question/problem I am hoping someone can help with.

I just bought a 69 Camaro convertible that is a rolling shell with all new GM sheet metal hung, and the majority of the rest of the car came in boxes and pieces. To think I sold a 68 convertible driver to buy and restore this thing; why are we all so sick?

Anyway, the 69 is missing the passenger side bolt-on brace that runs between the reinforcement behind the door opening and the reinforcement on the inner wheel house that also mounts the rear of the convertible top assembly. This piece is not available repro, so if I want it, I'm going to have to hunt.

So, my questions are:
1) Does anyone know exactly what this brace is called, and what function it serves? In other words, if it's not on the car, what happens? Having owned and restored the 68, I am familiar with all the bracing on the 'verts, but I'm just not sure how key this peice is.

2) If it is important, would it still be important on a car with weld-in subframe connectors? The 68 had the frames tied, and I'm good friends with the new owner, so if it isn't important after the frames have been tied, I might be able to buy that brace back from the 68.

3) Anyone know where I can hunt for one? I've checked D&R, Rick's, and two local guys that have used stuff, and no one has it. I'll be at the GM Carlisle show in a few weeks to hunt there, but if anyone knows of a Camaro/Firebird Junkmaster General, I'd love to hear about it.

Thanks in advance!
Eric
