Hmm, was hoping I could just swap brake drums to correct the bolt pattern, but if the R&P's are different it might be a pain to find ones to match the front. Thanks for the info and keep it coming if you know more. I found a site that listed the 4wd axle widths so I'll compare that to this 2wd axle.
I want to know also. I just got an 1981 toy Pu and I am going to swap the engine and auto trans. I would like to use the rear but fear the R & P are different. And I am not sure of the lug pattern and I think that it has a center set pumkin.
