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.
