I have a hitch mount that I bought from Yota Jim's in Denver that we thought would fit my 1988 4Runner, but it doesn't quite. After talking to potential buyers, it looks like it would fit a 2nd generation Toyota 4Runner (1990, 1991, 1992, 1993, 1994, 1995). A truck with rear coil springs like on the 2nd-gen 4Runner, would also be a fit.
The bolt holes line up with mounting holes on the frame of my first-gen 4Runner and older Toyota pickups, but the leaf spring mounts interfere. The mount could potentially be trimmed to fit around the leaf spring, but that's beyond my level of expertise.
In addition to what I paid Jim, I've had it sandblasted, then primed and finished it with a rubberized black undercoating from Rustoleum. Happy to send additional measurements on request.
