I have a 1970 GMC 3/4 ton with a three speed transmission, I am wanting to change it to atleast a four speed or maybe even a five speed transmission. What would be the best transmission for this aplication? Where can I get one for this truck and would it mount up to the origenal bell housing? The truck has a 350 in it so I thought it might be an easy swap out.

The taxpayers are sending congressmen on expensive trips abroad. It might be worth it except they keep coming back!
