Soft Doors Question from MWB

Greetings SWB. I'm hoping someone over here could help with a question I have. I'm looking for a place to get supplies for making soft doors for my Cherokee. ie canvas, channels, snaps, and window material. In particular for half doors I'm looking for the channel in channel anchor on the bottom of the upper and the top of the lower door like on the YJ's. I'm sure any info you could provide would help greatly as I'm still in the design stages. Thanks very much! Nate/DrZippo MWB
