It’s not that simple. Just can’t swap tail housing. You have to swap output shafts and tail housing. Can be done, but costs are a factor, could be cheaper to trade with someone...
My thought was to leave B body tail on it . Our shift farther forward where I kinda want it. A body shifter put it right where my bench seat is. I think I’d rather it 2-3” closer to firewall . And get a drive shaft cut . Am I missing something ?
