I ended up driving to another dealership and ordered 2 packs (10 total) of the nylon window roller Bearings and 1 packs (20 total) of the door panel retainers . Total price was $ 37.46 after state sales tax.
The part numbers are:
GM P/N: 10161510 - Plastic Door Panel Fasteners (20 Pack)
GM P/N: 9666748 - Nylon Window Roller Bearing (5 Pack)
I was going to order from GM partsdirect.com. but after shipping I would have paid $ 3.00 more for the order (I guess I'm a cheap scate
)
If the weather is nice this Sunday, I'm going to install them. If I can rember I'll try to snap a few photos of the insides of the door and what not and post them.
Thanks again for the information, you guys saved me a few hundred $$$$$!
