From experience, AMD is good for sure but I would check with Dynacorn. We really have never had fitment issues with their parts.

Really???? Man I wish I could say that. I can say that I've never NOT had some kind of fitment issue with Dynacorn sheet metal.

X2!!!! I stand by my original comments its all SH^T!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!

I have never used dynacorn, but did a lot of research before choosing AMD for my car.

The consensus was AMD rocks, dynacorn not so much. Also there complete shells also vary in quality.

2 of my first gens need the driver's door. Does anyone know if there are different ones being made? From what I've read everyone is selling the same doors.

A friend put on a 68 Firebird new doors, and it fit fine. The problem with aftermarket sheet metal is at times it fits fine and other times it doesn't fit at all. Now the fit was horrible with fenders, quarters, tail panel, hood, etc.

Another option is just fine a good used door.
Here is a few places to look, but Rick might know some more places.

This is a California junk yard, but has lot of old cars.
