David: did you make the plexi side curtains yourself? They look just right. Getting a little curve at the front to join in w/ the windscreen is a good idea, as Gordon says, but maybe tricky if have to use the heat gun and hope to not overdo it. I also hear that the special weather stripping that Henry uses on his roll-ups can be applied to a good end when using the plexi SCs against the windscreen. That rubber is a little bulky, so maybe would not look all sleek and such, but is sufficiently large and flexible, looks like, so as to make a good seal when squashed against the door. also, there is an old weatherstripping product called mor-tight, which is a bit like modeling clay, comes in cords, and one could fashion a dam w/ a little of that like your wiper blade. It would just stick to the paint; push it around so as to fill the crevaces just so, and you're done. peel it off when the weather will be good for a while. No more trouble to apply than blue tape . . . Just an idea, have not tried it. Right now I am all talk, as I run w/ crappy fitting SCs that came w/ car, and carry a big towel.
My builder said he'd make me new side curtains if I would make custom patterns of the exact size and shape I want. We have not haggled about the fee for that. I think if the SCs are made to tuck into the top flaps just right, much is gained. Jack has accomplished that w/ his sew-on extensions. Also Dusty (wonder how old Dusty is doing these days??) had custom SCs made, I think, and they worked very well, says he.
PS for toll booths, once you have it all buttoned up tight: get an Easy-Pass. ATMs? Who the f--- needs cash? Plan ahead and take what you need w/ you. Anything else I can help you with??
There is much research to be done at Carlisle this year. Very much looking fwd to all of that, and a few impromptu tech sessions too.
