1978 grand prix chevy 350 swap
I have a chevy 350 and turbo 350 tranny inside of my 78 grand prix right now but I am having a hell of a time with the motor mounts. I got motor mounts from napa for a 1978 monte carlo with a 305 (the same mounts used for a 350, I checked the napa part number) but these mounts will not bolt up. Do I need to drill new holes for these motor mounts, or should I just weld the new ones on? Or did napa give me the wrong mounts..... which is very possible.... The old ones have three bolt holes on them, and the new ones have four which do not line up with any other holes on the frame...
