what can we still get from gm?

[CG]

seen alot of threads recently that say...you can still get those from gm.
hood hinges, license plate holders, fender wells, later model side markers that fit nicely, etc etc etc. would those in the know consider posting what parts they know you can still get from gm with a part number please. even a part that might not be originally for our trucks but make a nice edition....like those side markers for instance....thanks.
