Well just installed my goodmark rear quarter on the passenger side. Overall I would give it a good grade. It went on smoothly and seems to fit and look real nice. The lines look rear good as well. Here are the only things i encountered. On the top edge at the rear of the car its not quite the same. When I put on the tailight housing the side and next to the trunk are perfevt but right on the corner it about a 1/4" low. I suppose i will have fill it to bring it up to where it needs to be. Another thing I noticed is the corner that is round where the trunk sits down in isn't quite shape right either not enough of a radius. Before I put the quarter on I lined up the doors and fenders and checked the gaps with a set of calipers with the new quarter on the gap is about .050 to big and there is no way to move it up any more because it would through everything else off. So I suppose I will have to center the door gaps on that side it shouldn't be that noticable at .025 more a side. The only other thing I saw was on the door jam area there are two indentations that were not on my original quarters they may be on a 67 I am not sure if they are they must have copied it from that. I suppose they could be filled if you had to. But again overall I would say its well worth the cash for a repop.
