...I have two sets of trim, however the trim clips are nowhere to be found. i have contacted every source I know to no avail.. The clips I need are approximately 7/16 ID x 1", they slid over the stainless trim to hide/close the joints. ANY HELP THAT SOMEONE MIGHT HAVE TO SUPPLY ME WITH THE FOUR CLIPS WOULD REALLY BE APPRECIATED. ...
Wm L,
Sorry this may have taken a bit of extra time to get a reply posted in here on the quoted question above. A search of GMPartsWiki resulted in identifying that the original parts you seek are listed as GM# 3818416, Cap, molding and used on ALL 1961-66 truck cabs with the "delux equip" windshield trim (Parts Group 11.208).
According to several different Master Parts Catalogs (extract pics added below), there were "4" used on the front windshield trim and "2" on the rear window trim (all the same items) for the '61-'66 Trucks.
That same part number also showed up as being used on 1960-64 Corvair (4 dr sedan - "2" on rear window chrome trim) and 1961-65 F.C. Corvairs (Pick-up and Panel Truck models - "4" on the front windshield chrome trim). I added this info just in case you may come across any of these vehicles in salvage yard as they could be donors for your needed clips.
A search of the web found just "1" of these GM NOS parts being offered (not mine)
from this seller.
Hope this info may be of some help. At least you have a bit more info on where you may be able to find more clips from other vehicles they came on.
Don't forget you can post your own ad in the
Truck Parts Wanted forum to see if any fellow Bolters may be able to help you out.
Good luck in your search.

Dan
