I am looking for some advice from you Buick guys. I do alot of Pontiacs and Chevys but this is the first Buick I have done over in my shop, its a 72 and I just bought a one piece trunk floor pan for it. Of course it comes through for Chevelle and the tail end section where it connects to tailpan area is TOTALLY different. I just finished a 68 GTO for a customer last year and I noticed how similar the trunk floors are to the 72 GS. Does anyone know if this older GTO pan is the same as the 72 Buick? It looks a heck of alot closer than the 72 Chevelle trunk pan thats for sure. I know I could cut and graft the Chevelle pan in but my issue is the Buick rear brace/pan area is in tough shape and I would rather replace it all. Any help would be greatly appreciated! And I am new to V8Buick so if there is a better place for me to be posting this question please let me know. Thanks!

Yikes, that restoration is definitely not for the faint of heart. I'd be interested in seeing what the differences are. Pictures would help. The area behind the rear seat does vary between years because of the vapor return standpipe in the 71/72's, but Im pretty sure you already knew that
If you are talking about the passenger area floor, yes, they are all the same. I ordered one from Ames, the GTO people, and installed it in a `70 GSX, no problems, fit like a glove. Now, the trunk floors are a different story. Those are generally brand specific.
I am sorry I didn't mention this is a one piece trunk floor I am speaking of. And yes certainly not for the faint of heart, its pretty intense. I'll try to get some photos, thanks guys. - Jake Facebook.com/ResurrectionAuto
My fault, not yours. You did mention it was the trunk floor in your original post. I was awake but apparently my brain was still asleep that time of the morning :sleep:
OK, if you are using a complete 68-70 floor pan from the firewall to the back of the car From the firewall to the back of the rear seat; The floor pan/rockers etc of the repro pan will be the same with the following exceptions; 1. The nuts welded to the floor pan for the front seat will be rectangular on the repro and round on the 72 buick 2. The bolt hole spacing for the rear seat top, where it bolts at the bottom will be different. The hump over the rear axle, behind the rear seat; That will be different because it has the hole for the gas evap system. This "area" would be the same for any 71-72 A-body. The trunk proper, from the hump to the triangular brace at the back of the car. I don't know if the Pontiac trunk pan has the triangular brace or not, but the Buick and Olds trunks do. If it does you can drop in the entire trunk pan with brace, and then splice the original trunk pan at that point. So the only thing you are keeping would be the trunk pan from the top of the brace to the rear of the car. If you look at a pic of a 69 Chevelle Dynacorn trunk you will see what I am talking about. So to sum it all up you would need to splice the repro pan just before the hump (at the factory weld would be nice), leave the original hump, use the full trunk with rear brace, and then section the last foot or so of the original trunk back in. Then deal with the retained nuts/ bolt hole spacing. Duane
