Just installed some chevys in the rear of my yota, they work pretty well. Anyway at full tuck, my 36x12.5x15 actually rub my rear bumpstop on the frame! And I just bought these rims and tyres! My ???---Should I invest in a newer rear axle--86-94? That is 3 inches wider. or should i get some more rims with a wider ofset?? I have an 84 now. Help need this fixed by the clean up. Like to go without any problems.. thanks --
