First, thanks for posting the answers to almost all my questions before I have a chance to ask. Now for my unanswered one. I have a four link rear end with coil springs with air bags inside the springs. One of the bags is torn and flat, the other seems to hold air. I am trying to replace the bag with the original equipment if I can find out the manufacturer. There is a window decal that says "Burbank Suspension", but I can't find any reference to them on the net. The Chevelle has been in the family almost 20 years and no one seems to know much about that end of the car. Any help with a source would be greatly appreciated.

Thanks to all

I would just replace the bags with some air lift bags and be done it.
