Second Gen cab light anchors

I picked up the correct set from a junk yard for my 1996. The trouble is that I need some nylon anchors.

I have a set of cab lights for my 2001 that I bought from the dealer. These are the anchors that came with it and I need to find 10 more for the 1996.

Anyone know who would carry these? They have a 1/2" head, a 1/4" barrel and are about 1/2" long.

Thanks
