Kelsey Hayes longer wheel studs

OK, I have researched this subject enough to know that there are no available options for longer wheel studs for the small bolt disc brakes.

Reading through an older thread on this very subject, Oklacollecto posted an image of longer studs available in Australia through Pentastar Parts.

These seemed pretty cool and looked like they might work so I was going to be the guinea pig for these things. They are really expensive though so before I finalized the purchase I sent an email to them asking to confirm the specs.

They sent me the dimensions from their manufacturer. Here's what they said:

... "hi greg, from our supplier catologue, the following specs
knurl diameter 14.3 mm length 73mm , shoulder 22mm .
sounds a bit short to me"

The knurl works out to be basically the same as the .565" @ 14.3mm. The thing that I am unsure of is the shoulder length. The shoulder on the OE studs is 1.062" or approx. 27mm, the Aussie ones is .866" or 22mm. This would be around a 1/8" shorter shoulder length.

AFAIK, when the OE studs are installed in the hub/rotor, the shoulder sticks out a little bit. How much, I don't know. Probably not a lot.

Think it would be OK to run these with the shorter 22mm shoulder?

Obviously I don't want to run into a safety issue and waste an exorbitant amount of money getting these things here only to find out they won't work.

Any input is appreciated!

Thanks,
