This winter I finally had to put my top up because it was just too damn cold at 6am to drive anywhere without frosting my pettiest. After a couple trips I came to the conclusion that it was definitely more comfortable with the top up. BUT what a pain in the drain (if not downright dangerous) it is to drive with the top up and the side curtains installed. I seriously think that more than 50% of my visibility was obscured in all directions. I couldn't even see stop lights without having to scoot down in the seat ! Well that just changed. I bought some 1/4" Lexan. Made a wooden pattern of the existing side curtain. Re-drew a new and reshaped wooden side curtain. Made some new aluminum side-curtain mounting pins and changed it all out.
The first thing I did was go down to the upholstery shop behind Kirk's old and Greg's new shop in Hawaiian Gardens and had him trim off 1 1/2 inches of the inside side curtain flap (but retain the two snaps at each end). This makes the side window openings much higher at the top for improved visibility. At first I was worried about rain getting in more than it does and dismissed that because this top and side curtain set up is an absolute leaker anyway. Besides, I couldn't see where that extra lower inside flap was doing anything anyway.
With that said here's some photos. The second photo shows how large the side curtain opening is now that the inside flap has been cut back to equal the outside flap. Oh...when you polish the edge of 1/4" lexan it has a lavender tint to it....kind of cool !......Bruce
