tech question!!!
my tranny is the old style c4 from 68 will it convert to a 89 mustang gt motor if i switched the flywheel i heard there differ splines?what would i need to convert? motor mounts? and what else?
With the correct flywheel, it should bolt right up. The splines only come into effect with the converter not the engine.

Sorry, we don't answer tech questions in here 
J/K, naturally Joe is correct, you'll need the corresponding flexplate and starter. If this is going into a fox body, I think there are fitment issues with the funky dipstick mounting the early case used. Other than that, you'll just need to order your parts for the correct tranny.
