as mine is a later car it is a slightly different design to the earlier cars , the innards are slightly different in the amount of air they let through as they close , though it fits perfectly to all V12 cars with the mechanical system.
i have a tested and fully working ( sealing off the air ) in a smooth action and allowing the idle screw to bypass some air to set the idle speed ,
this was removed from a 60k mile 1980 car , and is USED
this will be supplied with a new gasket , i bought two as i needed one for my own car
looking for £80 posted ono . as they are £250 new from Jaguar or the internet..............
