C20 Longhorn tranny swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So my wife smoked my original th400. I unknowingly bough a bop th400 and (what I'm assuming is the tail piece) is like 4 inches too long on the bop. So I unbolted it thinking I could swap tail pieces, and no go. The shift is one long piece. (I'm new to transmissions so this was all news to me) now I'm thinking I can just replace the front driveline with a shorter one, but have no clue on what information I need to go shopping.... I'm assuming just spline count and length. Can anyone advise?
