so far i've found one, its uhaul p/n 75031 which is a class 3 (funny that they have a class 3 hitch for such a small truck but won't let you tow anything that would require a 3 hitch with it). I'm looking for options for a hitch, i still have a the stock bumper on it with the ball mount holes but i don't think i would trust it for long, its rusty and crappy, but it has been able to pull some major logs even breaking a chain or two without moving so idk. anyway, can i get some p/n for hitches that will fit.

 

I have one that I took off of my '88 2wd. It appears to be custom made. I took it off because the spare tire would not fit with it installed. I do not know where you are, but if you want to come to northern California then you are welcome to get it out of my yard.
