News:
I just put a caliper on my knurling, and it read in the .660 range. I had some variance so I don't know the exact number.
I found this useful when wanting longer wheel studs?http://www.dormanproducts.com/Pages/hardware/index.aspxhttp://www.hpaulin.com/Catalogue/WP513.pdf
I see they have the 1.75" studs I'm looking for, have you bought from them Brad. Never heard of H Paulin?
