Good stuff Bill.
It's worth doing a lot of test-fitting of the windscreen, before committing to a final fit as, from memory, it's a very tight fit, and can be awkward to keep aligned with the edges of the opening - it wants to either sit 'proud', or flip inwards.
I recall one I built about 35 years ago, where I cut off the 'sliding' side windows to allow a better fit, and inserted a sliver of clear sheet at the rear of each opening, to represent the forward edge of the open windows on each side.
