There is a difference in some truck cranks vs. auto cranks. You have to look at the flywheel flange to make sure it will work. The car cranks have the thin the flange, some of the truck cranks have a thicker flange (about 3/8"). I have a truck crank in my GTO now. It has the car flywheel flange thickness and works fine. The only other thing is the truck cranks are not gun drilled through the mains to improve bay to bay breathing.
