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

[George Jones]

I'm in the process of purchasing a set of 16" IROC-Z wheels for my '67
coupe. Since these rims are thicker than the steel wheels, I am looking at
replacing the Corvair wheel studs, but I don't want to switch to the metric
studs. I'm finding the replacement stud decision is a little tougher than I
first imagined it would be. So far, I've found that the factory studs are
1.5" in length with an 11/32" shoulder and a knurl diameter of 0.472".
Dorman sells a set (610-157) that is 2.125" in length, which is near perfect
length, but the knurl diameter is 0.487". How hard would this be to pull
through the existing Corvair (0.472") holes (0.015 interference)? My other
option is a Mr. Gasket (4310G) set of studs that is 2.625" long with a knurl
diameter of 0.480" (0.008 interference).

For those of you running IROC-Z rims, what did you do to engage more than 3
threads?

Thanks,

George Jones
