budget 88 b2 build

[4x4b2]

hey guys ive had my b2 for about 3 months and i love this truck, im 15 its my first working truck and its so awesome. i know alot about mechanics but dont havee alot of cash so im trying to build this with the least amount of money possible. well i paid $200 for the truck, and have put about $20 in for lots of parts i got off a freinds ranger. and got lots of freebies, but now need to break down and get new hubs, my driver side is fine but my passennger side is badly worn out and needs replaced. i woud like warn hubs but sadly they are out of mmy price range, so if anyone has the passenger side manual hub that they could part with, that would be greatly appreciated, i can pay for the hub and shipping. or if someone has a set of warn hubs for sale for cheap ill definnetaly be intterested. now for the questions lol, how do i figure out what kind of rear end, transfercase, transmission and front end are in my truck? it is a 2.9 v6 and a 5 speed manual. i will ttry to get pics up tommorrrow but ou can loook at my youtube videos of it, ill put the link below. thanks in advance for your help, and thanks for reading
