I need some help from anyone with knowlege of NOS part numbers. I have a set of GM NOS window felts that are still in the package. The package is in very poor condition & the part number is hard to read. I believe I have it all except one number, but I figure it should be 0-9, so I think I can figure it out by changing that one number til I find a match.

Anyhow the number is as follows with the question mark being the one number I cant read:

GB.10.710.1.77288?0 STRIP

If anyone recognizes this number, has an NOS part number book, or knows someone I can contact that may know it, please let me know.

Thanks!
