deal wanting fronts piece
just spoke about this over breakfast this morning --
with my marine friends
it is a very easy process indeed -
it will be a year before i am even close to setting up to do this -
and in my mind i assume the rubber weather strip is same as the one around
pop top
will not know until completed
yours
