Reference help

Someone, somewhere near you must collect showroom brochures, or maybe you can find somewhere on the net, or in a Chevy magazine? there are, I know, specialist Chevy tuning companies around that advertise in the mags. Once you have the pictures, given that you know the wheel sizes in the pics', you can work out the dimensions for the panel lines. Failing that, can you find one in a scrapyard?

Yes, I can definitely work out the geometry from good square pics and the basic dimensions. The net's been worthless, un fortunately, but the scrap yards are a great idea. I'll have to get out there. I want to model a local police car from the late 70's, so the police museum may be a good place to hit as well.

Thanks for the tips.
