I am putting together a 1950 Olds Holiday Coupe, from boxes of parts that I did not disassemble. The question I have at this point is what type pf fastener did they use for the belt line molding below the rear quarter windows? There are 1/8" holes in the quarter panel. The molding is just under 7/8" inside width. I am hoping there is someone I can connect with that can answer this and some other puzzling things about the build.
