I searched and searched and found only one company makes a kit specifically for a 1976 Monte Carlo. So I orderd the kit from them. When ordering the kit the salesman offered me a few upgrades. I went ahead and bought 2 of the 3 upgrades. I upgraded to fast valves to raise and lower the car quickly and I upgraded to a larger tank. I didn't upgrade to electronic guages. When the kit arrived at my house I opened it up and found that the instructions were totally lacking. In fact they barely made sense. Further the salesman who told me that the instructions would be complete also told me that the kit had everything I needed. It doesn't have any wire for wiring the system and other pieces are missing as well. I called customer service, which was a joke, because they were extremely rude. I tried to explain that the salesman had told me I would get instructions and everything I needed, and the man on the phone told me that their salesmen would never say anything like that. I said "so you think I'm lying" and he said "Our salesmen wouldn't say anything like that." Eventually I hung up and knew that I wasn't going to get anything more from that company. I was hoping to install the kit in the summer of 2004, but the mechanics took precedence and the kit and instructions were lacking.
