Probably. I think the dogleg in back is the same, the doors are the same size, so that leaves the front fender. Measure everything, but I suspect they would. Mounting may or may not be different, but that my vary by brand too.

08 Toyota 4Runner. 4WD vacationmobile. No enthusiasm, but it didn't leave me stranded or use any oil. Reserving judgement for now.
M-Tech flares from an E28 will fit an E12 (with a change to the moulding on the dogleg), so the fenders are the same shape. Measure the length of your rocker, and I'll measure mine. That should give you the answer you need.
