I was thinking the exact same thing. All ya need to do really is put a radius in the front of the roof, and gap the doors. Find us a project, and I'll help ya with it...
Brian Bass out of Dallas did just that to a 29. He put a 32 windshield and header panel in it. Most people don't even notice the differance. The 29 also has a hotrodded 392 6x2 hemi in it backed by a 4 spd.
