My 89 has just air shocks in the rear with individual lines, they are the bottom license plate bolt holes, I do not need much air, just there for just incase at times.. Other pics are US 20in. mags with no air, It sat on the bump stops, other pics are way it sits today with Vision 5 spoke 18in. wheels, and air at 25 psi in rear. AIR NOT needed though. Drives AWESOME, handles like a go kart etc... To cruise and not ALL show only. Still need be careful in certain places with oil pan etc.., Rides beautiful !!!!
