[steven.0424]

can any one tell me if the running gear ie front and rear diffs ,transfer case and gearbox from 84 720 is the same as 86 d21, looks the same to the naked eye , both have sd engines

the question i have for you is the d21 a hard body (1986.5-1987). If not then there are miner differences. Key thing to look at is the numbers on the transmissions, then measure tail pieces if they match then they match if not then us the tail piece that you need.
