<VV> Wheel studs for IROC-Z wheels on a Vair

[Frank DuVal]

I just did this on the 67 sedan autocross loaner car that I bought Firebird wheels for. 

See: http://autoxer.skiblack.com/irocwheel.html

I just replaced the rear studs, the front were long enough. I used the Dorman part number listed. Different flaps use a slight variation in that part number due to different packaging. See the Dorman web site for the different equivalent numbers. Continue to use the 7/16-20 dimension. 

I did buy the Mcguard lug nuts listed in the article. 

No problem hammering out the 10 studs and using a cordless pact to pull the new studs in place. I used an old lug nut to hammer upon to remove and a different old lugnut to install.
