Window questions - window channel issues

[billybronco1]

1929 Model A Fordor Briggs

1) Is there a place I can buy the left & right window channel for each window with out buying a kit? Macs has the kit but I only need some footage of channel. You use to be able to buy this is in a roll by the foot.

2) What is the best adhesive to glue the channel in with?

3) Should I lube the channel with silicone or something?

Any other hints to have happy windows ???

Thanks
