well it finally arrived today ! a wide westy screen, so opened the box and with Trinas' assistance we tried it on the scuttle and quite pleased a small amount of reshaping on lower corners of the screen surround, and the lower section of the supports to bring them in a tad at the bottom , make a fillet up..... sorted not as much work as I thought so pleasantly surprised
will be a couple of nights before I can get back out there
and will add pics of before / after fitting
