What do you use your truck for, any heavy hauling. The is no direct replacement, most trans with an overdrive are going to require a drive shaft modification. I replaced the sm420 in my 63 C20 with a a833 - aka RPO MY6, it's a 4spd, 4th being an OD. I'm hoping the trans will at least pull a car trailer. Chrysler did use the tans in 3/4 ton Dodge trucks. Another popular trans is a T5 out of a Camaro or S-10.

I don't own a vehicle that isn't old enough to drink.
