Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) Side Windows - rubber/neoprene seals

Was at the 75th MSCC bash last week & noticed most side window seals were like the photo below. I think I need to change mine (2005 Plus 4) to the same. As the current seals I have fitted (the 2nd photo) are just foam / neoprene strips.
Does anyone have the specific details of the exact seal strip used & where purchased in the UK ?
