I strolled into a car trim company near to me, 1/2 mile from my workshop infact, got chatting, "A long shot I know, but would you happen to have screen rubbers for HB's" Expecting the bloke to fall off his chair in fits of histerics he tapped away on the PC and said "Yeah mate, how much do you want!"
Enough to do a front screen will cost £35. I will go back in to see about the rear screen rubber mitred corners, he might be able to do these also.
You will need to cut and joint yourselves chaps.
This place has got more rubber profiles than you can poke a stick at. I have a catelogue with about 100 profiles at scale 1:1. May even match up some door rubber if we are lucky.
