help i have a 86 custom deluxe with nothing fancy. i was thinking of putting air in it i have a 87 sub that is a parts rig and i can rip everything off that goes to the air. now my question is is it worth it??? it is reallly hot in oklahoma and i need help. most people tell me just to buy another blazer, but mine is in very good shape and it has the original 4 speed so i really dont want to give up my shifter. so what do you guys think?? how much do you guys think it will cost, and how much trouble.
