Thanks to all those involved with putting this togther Here is one of the type 085 G40 ATB diffs And here is the car its going to help keep the power on the tarmac for I have found a knackered diff nut & bolt i can stick in an envelope to one of you, should one of you want to drop it into a fasterners company? These are specialist fasteners, so would probably have to bulk buy at least 100 of each. They are very expensive for a set from VW and AFAIK only the G40 gearboxes in the polos got fitted with them from factory, so at least we can re-use them . Most of the polo diffs have factory steel rivits instead.
