It depends on what you want to do. If you want a LP, then a waggy 44 is the best option, and the easiest swap. If you want Hp 44, which is more likely, then you want a 44 out of a '71 - '77 F100 or F150, or a F250 housing as they are leaf sprung. You can swap between all the lug patterns, 5, 6, and 8 easy enough, but thats alot more info. You can leave the Hp 44 fullwidth or you can narrow it. Narrowing to use waggy inners is the most popular way to go, but some people do a different shaft length for each side. Waggy on one side and chevy or ford on the other for example. Thats the basic stuff, let me know if you need more specific info.......... :wierd:
