Ummm, that rear bumper looks like a Stout Equipment without the tire carrier.
I learned to drive a stick in the dirt. It didn't matter if I spun the tires learning. I also taught a young teenage girl how to drive a stick in the dirt using low range. I just had her pull out the clutch slow without giving it gas. That way she was able to see how the clutch worked.
Yes sir, it is a Stout bumper. My friend originally got it from them in ABQ back in the mid-late 1990's. He had it on his 1983 truck for years until I acquired it about a year ago.
