I just bought this last week and found out I don't need it. I have a 1991 GMC Sonoma needs a paint job but it runs and goes down the road like a new truck. Now it has Power windows, power locks (that unlock but not lock) A/C doesn't work new exhaust like new tires inspection is due, going to do that this week. No radio. its a club cab with a 4.3 engine with 120,000 miles on it last owner said he changed the plugs in it. The trans shifts good its a good running truck if a person wants it could have a matching fiberglass camper shell. So contact if you would like to know more or see some pics
