I have an 87 F250 with 460 and 4 speed, I have found an 89 F350 with a 460 and a 5 speed, It also has its transfer case with it.It is actually a whole truck.Can I take out the 4 speed and its hardware and put the 5 speed and its xfer case and hardware in its place.Will it all bolt up.I cant seem to get anyone on the heavy duty, crawlers,pullers post to respond.Also which xfer case will be in the F 350, it is stock.Thanks all that respond
