I disagree. The Goodmark rear quarters I put on my '67 fit 95% well. The only issues we found were an inconsistient gap along the passenger door (we ground the door a little) and the vent cutout on the driver's door jamb was cut at an angle.
Other than the rounted tail corners (not as crisp as the originals) we were pleasantly surprised and happy with how they turned out. We had more body work with the NOS GM fenders I bought than the Goodmark (full) quarters. You can scroll through the picts on my photobucket of all the sheet metal work. I have picts of the alignment issues.
I used to be indecisive. Now I'm not sure. I feel like I am diagonally parked in a parallel universe. 1968 400 convertible (Scarlet) 1976 T/A - 455 LE (No Burt) 1976 T/A New baby, starting full restoration. 1968 350 - 4 speed 'vert - 400 clone (the Beast!) 1968 350 convertible - Wife's car now- 400 clone (Aleutian Blue) (Blue Angel) 2008 Durango - DD 2008 GXP - New one from NH is AWESOME! 2017 Durango Citadel - Modern is nice!
