Where to get window slides???

Several links to those forward glass guide kits were posted in a recent thread. Expect to pay 50.oo per door average. Separate pieces of those kits aren't offered today although they were several years ago.
As for that plastic fastener glass to regulator, A piece of 5/16 neoprene fuel hose and 1/4 hex head bolt and nyloc nut. I use stainless hardware here.
Hope this helps.
