Ransil-
I passed the suggestions on to Serguei. The strap length/front/back thing makes sense. Bending the topic slightly, Another one of our soft goods made by Serguei popped up on You Tube courtesy of Brian at Build-A-Bronco. Shawn did a great job explaining them. I couldn't have demoed them better. Thanks again to the guys at Build-A-Bronco;

Serguei calls them "door toppers". I refer to them as SOFT WINDOWS. They are patterned from a set of NOS '66 pieces forwarded to me by TITO (who still hasn't collected on the trade, clearing my throat). Come on man, tubs aren't getting any cheaper.... ;D
Serguei and I spent a year reverse engineering these things trying to get them right. I think they came out well. Price is $365 plus shipping including the mounting plates. When the windows are out, you have a nice clean set of roadster half doors. Send him your zip, single or fixed vent style and color- black/white for a quote. Again his email is;
