Thank you for being there. I purchased a set of GM electronic rear air shocks for my 1999 Cadillac Seville SLS. They are installed and are working great. You saved me almost a Thousand Dollars. I still had the Cadillac dealer install them for $95.00. There original price quoted for both rear shocks installed was $1700.00. Buy purchasing from Arrnott I saved a bunch. Thanks again!
