There's a lot more to the simple look than running steelies. I've run those on my high option trucks. I started off with simple and basic, got all hung up on finding highest option trucks, then fascinated with odd combo of options, but my heart will always be in the most basic simple elements of these trucks that shows best with less.
Here is a truck owned by a friend, fellow member, swap meet buddy of mine. Perfect:
Here is the best shortbed 4wd I ever had. It was a '72 Custom with 292/4spd/4.10/front & rear posi. It had bucket seats/no console, tilt, tach, AM/FM, should belts, hand throttle, wood floor, fr & rr tow hooks. Lots of options, but nothing fancy.
