I run 1.25" spacers in front and back on my 83. I have ran 36 SSR's and now I am running 35" yokohama's . Little rubbing on the fender well but a sawzaw will solve that problem. You should be fine with the 1.5" spacers though even with the back spacing. Anything above 1.5 I think would run you into some rubbin issues. Wheel on!
