Hello to all. I want to swap out the 4 speed floor shift to an automatic. Probably a th350 or 400--depending on which I find first. The truck is a 70 3/4 ton 4 wheel drive. I looked in previous forums and couldn't find any info --although i'm sure there's plenty somewhere. My question--can anyone tell me what all I need to do to get this done. What linkage I need?--new steering column? (I was going to put in a tilt style anyway) Will any year tranny work? What problems I may run into? Any help would be greatly appreciated. Thanks Matt
