Well, I'm up to $19 in cost so far on my project. $3 for aluminum square bar and $8 each for two peices of 1/4" plywood. The patterns are made for both sides, and seem to fit quite well. I am going to try and find a source for Mar-Guard polycarbonate, because these side windows may spend most of their lives in a cloth bag in the back of the pickup with my lawn chairs. I don't want them all messed up from rubbing inside the cloth bag. I reduced the gap between the bottom of the sidewindow and the top of the doors to 1/4".--that way, in a "worst case" scenario. if I can't find a good premade seal material, I can glue a 1/4" square soft rubber strip to the bottom of the polycarbonate to close the gap and protect my paint. So far, this has been an easy project. I will post a couple of pics when I'm finished.
