Scott:
I apologize for being quick-triggered and rude. You didn't deserve it. You were just trying to get it right.
The good and bad part of these cars is that, even from the same builder, like VS, we don't know what the original buyer asked for with custom or different parts, and then, once delivered they tend to get "upgraded" by the subsequent owners. Just for front brakes sets, there are 4 or 5 different manufacturers out there that get used and then, depending on the year they're trying to replicate, they could go with wheel bolts or studs at 12mm or 14 mm. So you can see that it is difficult, at best, for us to guess what is on there without actually measuring it.
The first reply, from Al Merklin, was probably spot on and they are probably 14mm X 1.5, the standard VW wheel bolt size. Bear in mind that the bolt heads are probably VW ball-style to fit the depression in the wheel, not cone-shaped.
I guess I should have kept my fingers off the keyboard and gone to bed earlier. Sorry. I'll just shut up unless I have something positive to contribute, and you're right - This is a good group (my tirade notwithstanding) with a lot to give. Don't let me turn you off on the rest of us.
