I am restoring a 1967 Chevelle that I bought with allot of parts missing. I need to know what hardware was used to hold on the upper switch panel. The plastic nuts are molded into the plastic panel and protrudes into the dash through large holes. There must be some kind of cone washer and a small screw that hold it in. Any help will be appreciated. I own a '66 Malibu which will be a blown tubed pro street car, A '66 SS ground up stock, a '66 over the top pro touring show car - almost complete, a '69 SS396 4 speed bucket seat car - in the process of restoration and for sale? My daily driver is a 2 door wagon - converted with El Camino doors. All have big blocks. So I need to know how the trim attaches, the only car that is assembled has some kind of button head, probably push pins holding it in. Yes I will start some build threads on my collection. Thanks, Scott
