I am working on a friend of mines car its a 87 xt GL-10... the original air suspension is busted. he brought it somewhere and they installed aftermatket air suspension i think from a truck and did a bunch of other things with the wiring so that pretty much threw out me trying to repair the original air suspension... but i believe its to much for the car when he drove it he said it was bouncing all over the place. So I drove it to my house with defalted shocks... THAT was a fun ride... never laug
