Roof plug 11.

Started filling in passenger side.
The drivers side is pretty much set,
with two small sections to do, to complete this area.
I placed a sheet of plywood, along rear profile,
and carefully marked, and drilled small holes, to
guide ends. Then reversed sheet,
wedged against passenger side guides.
Side vent sections have been added, to drivers side, but will wait to fill in between, so as measuring for passenger side will be easier.
