webshot,
i just did this last weekend!
I got tired of the hole between the vinyl and the glass where it had seperated.
All winter i had to put a tarp over it so my car wouldnt fill with water.
The install is kind of a b*tch.
I am happy with the job that i did. It took about 5 hours but if i did it again i could do it in 2.
I bought the glass which is connected to the vinyl with the zipper at the top from 50resto

. It was like $150. I didnt want to do the whole top but i wanted that darn hole fixed.
I just started taking stuff apart and kinda figured it out. You will need a staple gun, LOTS of staples.
As the previos poster said you should probably get it done by a pro, but if your mechanically inclined its not that difficult.
Let me know if you decide to do it cause i got some time savin tips.
