Phil--
You said "I have the Nical hard top for my BJ7, as Steve mentioned it was a very tough fit. Drove me crazy for months, Nick told me its how they all fit."
The biggest problem I had with my hardtop was fitting the rear window. The one that Nick gave me in North Carolina when I bought the top was too small for the opening. He sent me a new one and then the fun began--because the BN1-2 top is so thin it would flex when pushed against and it was impossible to exert sufficient force against the top to jimmy the rear window into the aperture.
Finally I bought two of the rear window stays that were used on the factory tops and once I mounted them they triangulated the opening and made it stable enough to work the window into the rubber molding. I like the looks of the stays anyway as it captures the original appearance.
