Hey Guys & Gals, Gotta give a Holler out to Arnott Suspension Products for solving my bad Struts/Shocks problems. Have to admit that I was leery about replacing my OEM struts with Arnott passive system, well, I finally did it, and boy, am I happy with the results. Bought all four, front & rear from Arnott for a total of $478. My mechanic did the installation, and a front and rear wheel alignment afterwards(It's required) for $269 labor & alignment. He stated that the struts were made just for my car after I had ordered them, because the manufacture date, my name, my VIN # were stamped on the struts. Also said the installation went smoothly and all air hoses and wires went directly into all existing ports and connectors. The car (99 Eldo) rides like it just came new from the factory. I am extremely happy that I saved about $4000 from the quoted Cadillac dealer price for all four OEM plus labor.
Signed, One Happy Arnott Customer!!

Thanks for the info that's just what I wanted to know.
