I have about 1000 NOS GM parts from a dealership that closed in early 80's, Parts are from the 60's to 80's most still in the gm packaging. There are truck parts in this group also. Examples of what is in there are: lot of wheel moldings, original floor mats, brake boosters, cruise control units,seat belts,shocks, spedometer, clocks,loads of pin stripe. If you know your GM # go to my web site at BDenterprises2003.com and see what's there.
Hope some of this stuff will help somebody. It was just stored in an old warehouse when I found it.
Happy hunting.
