My first sports cars were Healey Sprites, Triumph Spitfires, and sundry models of MGs. On those babies you had to put up an erector set frame and then drape a piece of canvas over it with a multitude of straps and snaps to hold the whole mess together, so chopping the back window on the Box is a negligible problem.
I have taken the "chop embarassment" to a whole new level!
Because the elastic straps on my original 1997 covertible top are so worn out and stretched to the max, I have a little routine I must follow each time I take the top down by chopping the plastic window, then chopping the canvas above the window because if I don't, it makes the hole I have in it grow... the switch in the center of the metal piece that comes down to cover the top has made a hole.
Now putting the top up also requires manual adjustments due to those worn out elastic bands. both the left and right side of the top near the window framing comes out from the groove in which it should remain. I must raise the top half way and then run my fingers around the canvas to insure it seats well into that groove on both sides of the car.
Just as soon as I sort out my transmission issues (1st gear has teeth missing) I'm going to replace this top. Grrrr!
Transmission is being torn down as you read this post. My mechanic has a tranny in his garage that has 2nd and 3rd gears out (or the piece that engages these gears) and is going to take the main shaft and 1st gear (welded together, from what I hear) out of his and put it in mine. Let's all keep our fingers crossed that this works as it will be a cheap fix... he's only asking $1100 including parts and labor.
have you tried cabrioworld? Their offices aren't far from me, I've ordered from them in the past. They have the best prices on quality tops. Actually they are just a distributor but on a very large scale.
Their boxster tops start at $450
