I have yet to find one online. The problem with changing the top yourself is that the aftermarket tops do not have any of the aluminum reinforcements that go along the top of the window and across the front of the top where it meets the windshield.
You must remove these from the old top and gorilla glue them
exactly right on the new top or it will have creases or ripples in it.
I watched my mechanic do it for a forum member here in Houston and I was amazed at all the skill it took to get it on square, the order in which it had to be installed, and the gluing. Hans had done it a couple of times before with aftermarket tops, and a bunch of times with $2800 factory tops, which come with all the aluminum bracing already glued in the right places for a faster installation. You may want to reconsider doing this job yourself.
If you do tackle it, take pictures and document the work carefully for the forum. I think you'd be the first to post something on the internet about it. :dance:
