Blimey! Exciting stuff. Do you cut the whole roof off in order to be able to fit a roll cage?
It certainly does help but its not essential. The roof has been removed for 3 reason. Firstly the original had a sunroof, secondly the underside of roof had the sunroof mounting points which made it heavy and thirdly I have a non sun roof light skin to put back on.
The windscreen surround was removed because it had a rust hole, as I can but new it made sense to fit a new one as we are at this stage.
