Which are dismal.

I've known of 2 cars that were built with Dynacorn bodies (Camaros) at 2 different professional restoration shops. I know the body men well. Both finished the job and said never again...and both ended up charging the customer about $10K+ extra (unplanned/unbudgeted) to spend hundreds of hours to get the parts to fit the body and/or the body to fit the parts. Basically they both had to disassemble a large portion of the Dynacorn body at the spot welds, reshape panels, and weld it all back together. Not to mention straightening EVERY SINGLE panel to get them straight enough to look good in paint. Plus strip off the crappy primer from every nook and cranny and put a decent primer on it...

So basically you buy a $15K+ body, and spend another $10K+ (or hundreds and hundred of hours) to get the panels to fit and get the body straight, plus blasting it to bare metal and re-priming in order to accept a nice looking paint job.

Both swore they will flat out reject them in the future (or at least will simply be up front and say "OK we'll do it...but we have a $15K Dynacorn labor upcharge", and both said it would have been much easier and cheaper, with better end results, to just rebuild a rusted out body from scratch with individual repro parts, than to assemble another "new" Dynacorn body car...
