Got mine from convertabletopguys.com
The plastic edge that folds under the bottom was pre-formed the wrong way... It was a huge PITA!!!! all-in-all it probably took me 6 hours or so, a drill press, 4 drill bits, lots of swearing, lots of talking to myself, lots of short little "breather walks" and some laughter from my girlfriend. Got it on though. Looks pretty good. I would give myself an A-. If I picked it up and didn't know what the installer had to do, I would probably not even notice the small screw-up's on it. Looks pretty good.
The top is not a, "direct factory replacement". They do some goofy fold and tuck crap by the windshield that looks sub-par compared to the original. On the other hand, it still doesn't look bad.
Top was $300 shipped. came with glue, new cables, and OK instructions if you read them like 436 times and installed these tops prior.
OK, the instructions arn't really that bad.
