Hi all,
It took me some time and frustration to find this part, but I just wanted to post the OEM numbers and where I got it in case it helps anyone else.

This is the square rubber boot that goes around the ignition in the dash, and then the bezel that snaps into that. Note: I have a 2004 (6th gen).

I ordered them from gmpartsexperts.com. The boot is #10446064 & sells for $3.53 & the bezel is #2852049 & sells for $17.64.

Why did I need this? Since I bought Die Hard (the Monte) last year the key clicked slightly as it turned, with slight resistance. One day, the key would insert all the way. I fumbled around a bit and realized the pins holding the bezel in had broke and it was sitting out just slightly enough to not allow the key to fully insert. So, I am guessing the dash was taken out at some point and this piece was broke in the process. Luckily, it's a cheap fix.

FYI ... I got the parts today. They looked fantastic and we a snap to put it, but figuratively and literally. It's worth noting the rep from gmpartsexperts.com followed up, unprompted, with me when the order was placed and then again when the order shipped. I found the service fantastic.

 

great info, I've only heard bad news about them with the shipping times being terrible, thanks for posting...
