I know this is an old thread, and I've read through his step-by-step instruction threads, but I'm hoping the OP is still active here. I was wondering where he sourced the upper portion of the door panel? The section covered in the CF look material that has the door lock protruding through it and I'm assuming hangs over the edge of the sill?
I'm thinking I might give this a shot to build some door panels for my Firebird, especially since the rear sections would have to be modified anyway due to the mini-tubs.
These turned out great by the way!
