Brings back memories. I bought brand new a 1976 F 250 four by four regular cab 360 CI and a auto with 410 gears. I came with Goodyear tires big block tread and 16 inch wheels. Check and see if they made two different front axles as mine had a much bigger front locking cap with six or eight Allan cap screws holding it on . Manual locking hubs. That year uses a slave cylinder for the power steering that was prone to leaking. I was used on the farm pulling loads way more than it should like 6 ton fertilizer carts or a pallet of seed corn in the bed 3300 lbs I had it 26 Years longer than my first wife 23 years. Wish I still had it
