WOW !! many thanks to you all for your helpfull advice, screen is now fitted without to much trouble , used plenty of soapy water and fitted it myself this afternoon , had the glass cut local to me and was quite a snug fit in the rubber,my top tip is to use a small amount of super glue on the parts that keep falling of the rubber like the corners, The stainless trim held in tight , put the cord round and simply pulled it in , plenty of palm slaps and in it sliped stragely quite satisfiying when it finnly slips in ,used a screen sealer after it was fitted, saves ALOT of mess. looks good
Thanks again Lez
