Where To Get Info - 86 W250?

727 Transmission (or NP235 if it's a stick)with attached NP208D aluminum chain driven transfer case. Dana 44 in the front (Dana 60 if it has king pins instead of ball joints). Front hubs could either be full time (Silver discs in the center), or locking hubs (Lock/Free switch in center of hub). Shifting the vehicle into 4wd involves a vacuum chamber mounted on the front axle (Dana 44). Dana 60 FF in the rear. Fuel tank is probably 35 gallons.

BTW.....Assuming it's a gasser 5.9 and not a diesel 5.9
