UPDATE.

rang ford today for a quote and they want £123 inc vat for one and theres no way on this plannet i'm paying that so phoned ASM (which is next door to ford) and they've got one still on a car so i can have it tomorrow for £27 inc vat. comes with 90 day guarantee for exchange or refund so i'm getting that.

thanks for your help dave, much apreciated mate
