This has been covered I bet a dozen times in the almost 20 years I've been on the board. If you have 5 lugs and disc brakes, someone swapped them onto your 70 model truck. There were no factory 1970 disc brake trucks. They all had 6 lug 2x4 and 4x4 1/t tonners.

If the posi is gone I’d be willing to be that’s when the 5 lug stuff showed up.
