Hy Tomm, okay I did a bit more searching, Truck Components, toll free 1-813-933-1166 has their p/n 13-2006 which is an 11/16" thread .755" knurl 3.56" o.a.l. wheel stud which their description says replaces GM. This stud is over 3 1/2" long where the others are only 3 1/4" long, it appears to have the correct knurl diameter. I could not get a price as I am a ludite and couldn't figure out how to get them in my "shopping cart", hope this helps. Please let us know the results.
