i was given an 87 grand prix from a friend of my dads he just wanted rid of the car. it needs work but the car is solid. the doors are bubbling rust on the bottoms and the vinyl top is all tore up and the headliner is gone along with the cloth on the front two seats. i want to take the six cylinder out of it along with the auto transmission and drop in a built 355 with a 4 speed, get rid of the vinyl and redo the interior with bucket seats and maybe a roll cage. i do like the looks of the monte carlo. would i be able to get the front and rear bumpers to line up with the pontiac body?
