I bought a new Ready Made Top from Morgan Spares in New York for My +8 Bitsa. I have a 10 pin windscreen and Taylor Cam Tighteners. I installed the Fittings from the door back but not installed the fittings for the Windscreen. It is a very tight fit with lots of loose areas. The windscreen fitting will be the last chance I have of getting a good fit. Frankly it is so tight so far I fear that I will split the top when I throw the Cam Tighteners. I have the garage at 70 degrees and a small heater on the parcel shelf. I also have a heat gun but am afraid to use it. This is not Everflex but it is a Vinyl that looks like Everflex. I wonder how much stretch I can expect? Not sure if I should throw the Cam to tight before I put the fasteners for the windscreen or not? Anybody with experience on TM?
