By the way, I had 18*8.5 on all four on my 87`442, I dont think 9.5 would fit very easy in the rear without a frame modification. Atlast very Close. Is El Camino different?
I can try to find the spec and a Picture if you want, but it is "euro" spec with offset instead of backspace. I know it was ET15 rims (+15mm offset) And I did use very thin spacers.
I did put the specs out on G-body forum I believe.
Found the specs: It`s 18" x 8.5 front and back +20mm offset front and +25mm offset in the rear I needed the 10mm spacer in the rear or else it would hit the frame, in the front I did not really need the 5mm i put there.
(3.46 backspace front, 3.26 backspace rear whitout tires) This backspace I believe is probably just calculated from the rim size maybe, do not know. Maybe I measured from hub to lip of rim. anyway, as you can see I could not have much backspace in the rear without hitting frame. It was Stock 8.5" rear
The tires are 245/40 front and 245/45 rear
