yes, pal thats right,but i know for defo tickford definately converted some rs200's after they were already manufactured,they changed the spec for the customer,and have been told that that happened after the run ended for rs500.only a few,i new of a ford main dealer who only ran the top of the range fords,and his rs500 had leather and ac,tickford apparantly did it for him,before delivery.
i had tickford do a lpg conversion for me once,now though if you call tickford you get put straight through to prodrive.
as said earlier though,only left hookers i have seen are racing cars
