I'm making good progress on completing my 58 Chevy 1/2 ton but I'm having trouble finding the felt upper window channel that replicates the original design. I have purchased the cloth and felt covered segmented metal style but it doesn't have the clips as the original. I have seen article and videos of guys glueing these in, just doesn't see right to me. Does anyone know if correct style channels are made? Or I'd even purchase an old one and try to modify a reproduction to match? Thanks any ideas may help.
