Marc, i have kinda founf the thing you are looking for this is the same as the one i bought..

however bought it from a tool specialst which now slips my memory who.

i remember at the time looking through demon tweeks after spending about 3 hours looking for one on the net and they sell the same thing.

Price wise i paid about £70 all in

demon tweeks do it for £72+vat, but once you have it... your sorted.
