Ok, so I have done quite a bit of searching. I understand that the stock size of our lugs is 12mm x 15 inches, but what is the stock length of the mag shank for the z28 wheels from 84. I'm talking about the five star 15x7 wheels we all know and love. I'm looking to get some closed end lugs for a set of refinished wheels, and I want to get the right size if I'm going to blow 50 dollars on them. Thanks.

 

Any takers?

McGard has these lengths listed as the options:

.746" as regular

.946" as long

1.00" as long

1.365" as extra long

I'd guess they'd use .746? Can any one confirm this?
