I have a '73 z that I've been restoring for some time now. The guy who had it before me did some half-ass work on it including a half-ass paint job. I removed the Fenders, Doors etc. a few years ago in prep to prime and paint. Long story short, now I'm re-assembling it and notice in the assembly manual there is a right hand and left hand "Filler Panel" that appears to be sandwiched between the front top and bottom Header panels. I'm shocked. When I was removing all those panels, I never came across these Filler Panels. That's not too surprising, given the fact that the previous owner put it together without half the bolts or spring nuts required and the few he had in there looked like he bought them at Home Depot. What I find shocking is the fact that I never noticed them missing while the car was put together. Mind you, they are a flat piece of metal but you'd think I would've noticed some sort of gap where they should've been. And now that I think of it, I don't recall seeing them on other Camaros at car shows, etc. Has this ever happened to any of you? I bought a pair anyway from NPD but just found the whole episode strange; like what other surprises will I encounter when I re-assemble this bad-boy?
