Dave, look on V8 Buick, my thread under Chassis Restoration, My 66 GS body mounts. I bought 66/7 non Convert set from Ground up and the 4 plug rubbers from Restoration Specialties, and for radiator bought from them also, but I did not need a full set for the radiator and they need some mods. You will also need to mod some of the other, and will use the Ground UP on the four up front and mod two more for the ones under the door, Next 4 are the rubber plugs, the ones by the rear wheel I used some 68/72 ones I had, and used the Ground UP for the two rear. Walt helped me to find the correct numbers. I am not able to link the V8 thread. There is a lot of good info on the post thanks to all that helped me.
