I have a 1978 D150 Pickup. Short bed, Reg cab, black on black. VIN#d14bf8s144882. I recently put a built 383 w/ 727 under the hood. The truck came with air, cruise, tilt, cargo light, 40/20/40 cloth seat, tach and vacuum/volt guages. It has an 8 3/4" w/489 center. Not shure what gear ratio is in it, but it runs about 70 mph @ 3,000 rpm Currently looking for 15x8 or 15x10 steel wheels for ther rear as i plan to put on P315 70 R15 BFG's.
