Looking for a little insight here. 1986 Sierra 1500, Pancaked front cross member, PB 1inch narrowed, 1 inch forward control arms, 3 inch drop spindles, Z to get the frame rails on the ground. Really want to run the Detriot Steel Wheels Delray in 22x9. The largest backspacing they can make in a 22 is 4.5 I know I should be looking for 5.5ish but with the narrowed arms, any chance they'll clear the fenders. Haven't run a wheel this large, any opinions and experience appreciated.
