[urq] 1983 UrQ Polydrive head bolt

[Cardinal Control Systems]

	Can anyone please tell me the correct Polydrive bit size to fit subject head bolts?
	I have noticed that 10mm, 6 point is referred to for 1998 and later VW/Audi but can find no definite
	mention of the size for earlier bolts other than a vague 9 or 10mm, which is the distance across
	the outside points by the way not the bolt diameter.

	Incidentally, in the Bentley book they are referred to as 'Polygon' bolts which is not correct.
