85 Jimmy, here is the shopping list of the parts needed for the side window rebuild:
#34 on the diagram, flocked channel: SoffSeal part number E634. It is NOT an exact match, but it works and looks fine. They come in 8 foot sections, so you need 3 of them to complete 2 window assemblies. $18.61 each. Be sure to cut drain holes in the channel and make absolutely sure that they line up with the holes in the lower aluminum frame or you WILL have water issues. Also, you must cut "slots" in the channel to allow it to make the sharp bends, just like the factory did. Contact SoffSeal at 800-426-0902.

#36 on the diagram, filler: Atwood part number 132014470. It is PERFECT match. It sells for $0.10/inch ($1.20/foot). You only need about 8 feet, but they have a $20 minimum order. Contact Sue Phillips at Atwood Mobile Products at 574-266-4829.

#38 on the diagram, wiper: This item can be found at any residential glass shop or probably at any home improvement center. It comes in bulk, on a roll. I paid $0.50/foot for mine. Just take your old with you to match up to the proper one.
I borrowed the image from "Irish1941". Irish, I hope you don't mind.
Good luck on your windows! It's well worth the time and $.
