Hi Rilap,

I also have a 52, 1/2 ton that is all original. I am going to be swaping out the drivetrain as well. My thoughts are to go with a Heihts IFS, keep the 235 ci and use an adapter kit for a 700R4 tranny. Also, I'll have to swap out the rear end as well and install Mono leafs in the rear. This swap also mean I'll need a new steering column w/shift. The questions I have are:
Will I have to cut the firewall or floor in order to get the 700R4 in?
Anyone out there ever done this? I have installed a T350 trans a 53 Chevy PU without having to cut the floor.
