Remis roof window.

Decided to fit the large Remis tilt and slide roof window, it needed a 600 x 600 cut out. Overall its bigger and needs room at the front for the whole unit to slide forward.It was too big to fit in the indented area behind the cab seats,so I ended up fitting it further back. This entailed cutting through one of the roof struts.the roof was quite floppy! But once I had stuck the wooden frame up and fitted the window the strength was restored.As this was a big opening it needed more of the roof corrugations filling in.This was very time consuming and fitting this window took me all day Saturday.
