Yukon axles with weld draglites, what studs ?

Ok, ive looked around at some local autoparts stores, Kregens, Autozone ect. They all ask what year and model when it comes to the studs and given the fact my rearend is off Ebay, and studs are aftermarket they arent much help. I dug through the parts rack at Autozone and none of thier studs would fit. I am going to call Randys Ring n Pinion and see what they say tomorrow but I just figured I would post this on here now to see if anybody else has run into the same problem and could get me a part number or what not. Im converting to disks in the back, I have Yukon 30 spline axles and I have weld draglites 15x7s. I figure Id need a good 2 1/2 + inches of thread on the stud which doesnt seem to be a problem. Just looking for studs with the right diameter to press into the axles.
