Jaguar XKR convertible window sill trim corrosion.

[mordros]

I am new to PistonHeads so forgive me if this is an old topic. I have just removed the right hand lower front window/door trim due to bad corrosion. However the rubber trim insert has a metal retaining strip inside that has completely decayed causing the rubber to split and bubble. New trims from Jaguar are silly prices. However I did see a thread from Rob47(?) posted in 2015 saying that he had had made some neoprene replacements. Does anybody know if these are still available?
Thank you in advance.
