I would like to do that on my Barracuda. I think the back window would fall right through the hole. I could weld in some 3/8 round stock. I have 68 Stainless mouldings I can use. Damned I cant even remember where I got them from. 67 has the plastic insert. I thought glued in with a generic vinyl molding and some faux bolts like nascar would be cool.
