Just read through this for the first time, i have an early narrow bodies series one and a hard top! :shock: i know haha. Dunno how my car came about having it though. But its pretty much atertight bar a tiny gap at the front edge where water can drip between it and the window right onto your right knee
Although, the top wasn't built to fit the glass windows and had race pollycarb windows, so i now have to go and make a few bits of fiberglass to bond onto the hard top to follow the curve of the window, so i get a proper seal.
