The early, re late 70's hilux were the same width and Spring saddle spacing but pretty rare. My own car has a mid 80's hilux which is 2" wider again and I had to move saddles in but ive still had 205/60 13 on the old kidney style 6x13 alloys with some lip work done. A 90's hilux 2wd diff I picked up has an offset diff centre so a bit beyond a backyard job. Hope that helps. I've been wondering about a mid 80's Toyota crown, apparently same centre as a hilux but has discs, have yet to find 1 though.
