I've written previously about my '05 LeSabre radio and minimal body control swap into my Caprice.
Yesterday, I switched over to SiriusXM's channel "The Bridge". I had to laugh, as I though the radio was sending me a message! ;)
Jerry here. Original owner of a 1996 Century Custom (175Kmiles). Also have a 1992 Century Special with a 3300 and 4T60 with 211K miles. Bought it from an elderly friend, actually a far better car than the '96.
Lots of experience with GMs, as I'm a nerd and a gear head.
