I am currently looking for one of these units. There was one recently on eBay. Apparenlty you don't NEED to buy the DRB II specifically. The DRB II is a unit produced by Chrysler. There are other units made by other manufacturers that will do the job. The trick is to find out which unit will work for your car. Personally, I think I'd like to stick with the DRB II since it is specifically referenced in the diagnostics mauals. ----- Original Message ----- From: Bruce Phillips To: Sent: Sunday, December 14, 2003 8:03 AM Subject: IML: 1992 air ride test tool I Have a 92 Imperial with an air ride problem. I have repaired the electrical connections in the front fenders and replaced the air ride computer. I can make all of the system work individually if I jump the connections in the trunk and I have tested the limit switches on the struts. My manual says there is a DRB II test tool for this system, Does anyone have one the would like to sell? Thank You Bruce
