Part number is JGE000070 and I think the RHD version ends 000060. Try putting that into Rimmer's part-number box. Breath in; they are now 250 Quid!

£159.93 + VAT though , which is what I paid Nick at Austin's for my 00070
Googling just on "JGE000060" will bring up quite a lot of options, but I couldn't find one cheaper. Nick may have one ??
Best check that JGE000060 is correct for RHD; I know my JGE000070 is the correct valve for LHD.
Edit: haven't fitted mine yet. Nick say's its a dash out job :-(
Maybe just the console unit is enough, but I'm not banking on that. LHD is different anyway, some bits being handed, some not.
