Hey guys, need to know how long a stock drive shaft is, and how long it should be. its a 84 cutlass, it had a th250, has a 6" tail shaft, and a 7.5" rear end. i think the drive shaft was just about 54" end to end. now i have a th350 with a 9" tail shaft, so the drive shaft would have too be 3" shorter correct? i just wanna know what too tell the drive shaft shop for length, or if there is a car i can find one with a length i can use. thanks in advance.
