Linda, I have a 1988 sunder 21' with the 142" wheelbase. is that the stock wheelbase or did they move the rear axle back? Just trying to get an idea. I have found a 1988 4WD Toyota pickup (Terrible body, solid frame) that i was considering swapping over. Just don't know if it will fit, without measuring the 4wd frame. All the diagrams i have looked at list the wheelbase shorter than that.
