Well, I stand corrected and I must apologize to anyone I told different. While servicing the rear brakes on my 1990 Imperial today, I had a good look at the rear suspension system. I'm not exactly sure what was there originally but the PO had installed air shocks in the rear as a replacement to whatever was there from the factory. These shocks are fitted with a manual fill valve near the rear of the car. The shocks are worn out so I have to replace them regardless. This car has a regular coil spring also. I was under the impression that it had an air spring such as what is detailed in the Haynes manual. I guess the manual doesn't cover every type of system. I now have two options... 1. Replace the rear shocks with the Dynasty style shocks and live without air ride. I am thinking that it wouldn't take much to overload the rear of that car with a couple big passengers and some trunk cargo. I sure would like to have air springs at least. 2. Replace the rear shocks with the aftermarket air leveling type of shock. Those were listed for over $100.00 each. This is a viable alternative and I could use either a manual fill system or a mechanical leveling valve to automate the leveling. The Dynasty shocks are cheap enough that considering the amount of money I have to spend on the car to just get it drivable, I will probably go that way to start with. If there is no problem with the car bottoming out at all, nuff said. If there is, I can devise air ride after the fact. Thanks to all those who have lent their opinions and experience. I'll keep you up to date on my findings and what I learn.
