This guy on ebay has all types of GM stuff. I got my intake (http://www.cadillacforums.com/forums/#) plenum for 19.99 and I got all 8 intake gasket things for $12.xx. I forgot the change. But anyway, he sold me all 8 for less than $13 total. He has some other stuff plus some GM stuff. All new stuff. He claims stuff came from a closed GM dealership. Not hard to believe. Anyway check him out. You might find something. http://stores.shop.ebay.com/Knight-B....c0.m14&_pgn=1 (http://stores.shop.ebay.com/Knight-Beads_?_sid=23104471&_trksid=p4634.c0.m14&_pgn=1).

A lot of Caddy parts here.
