I'm a long time Chevy man, but just recently have gotten into building a 1980 K-5 as a purely off-road machine. The starter vehicle comes with a NP208 from a 1984 or 1985 K-5 that was equipped with a 700R4. I have two TH350s (both late 70's) and was wondering if the 208 is a direct bolt up to the TH350 using the adapter plate from the TH350 or the 700R4? I am posting this question prior to purchasing the base K-5 to start. Both 350's were orginally coupled to the bohemouth full time TC (which I still have).
