I have a '93 4runner with an automatic, a friend has a '90 model with a 5spd. Long story short I plan to give him the engine, but one of my brothers friends, a toyota dealership mech says that some of the autos do not have provision for a pilot bearing in the crank. I think that he is smoking crack, why would toyota have 2 different cranks for the same engine? Am I wrong? Am i going to have to pull it out & look?
