What is that set-up. Looks totally different from my 74 PW W100. My SB trans has a short drive shaft from the trans to the divorced transfer case. Is that an overdrive unit? I want to go with late model Hemi in the truck and told the BB case is the way to go. I figure I can use the SB tail and main shaft on a B.B. case and get there. Kinda the opposite of what you are trying to accomplish.
