[V8Vairs] V8Vairs Digest, Vol 75, Issue 3

Sat May 14 06:34:09 EDT 2011

This is what I used on my V8 Vair for disc brake conversions and now on my 
race car for wheel studs.
NAPA (Balkamp) wheel studs. PN 641-1268, 7 /16"-20 x 2 1/8" Long with .487 
knurl.
If you use a closed end lug nut be sure the end of the stud does not contact 
the nut before it is fully tightened. In my case with the fancy lugs on my 
V8 Vair I just trimmed the ends of the studs accordingly.
On my race car when I used the same nuts I just ground down the end of the 
lug nut so it wasn't closed anymore.
