Well, I took the studs that were recommended, and the new lug nuts I bought, and went over to dad's shop to change them out.(My tools and garage are 2.5 hrs away, and I'm trying to get my house and new garage built......) I pulled off the wheel, the axle shaft and the drum. I pounded out a broken one, and got a new one out of the box. I then pounded out an undamaged stud and compaired the two. The new stud is larger diameter, the same length as the studs that are in it, and the threaded section is shorter on the new stud! The new stud has the threads cut off about 1/4" from the end. The 1/2 studs that are in it now have more thread holding the rim on then the studs that I bought.
So the short of it is this. DO NOT purchase the part numbers above to try and upgrade, as IMHO they are not much better. When you thread on the new lug nut, the nut only turns about 7 revolutions before its up against the rim. The 1/2" studs are 12-13 turns.
I'm going to try and dig up the size and part number of a stud in an F250, about an 88-89 vintage. Even if I have to drill out the hub and the drum, I'm going to get these upgraded. Thanks Rumblefish for your help, I don't know what went wrong. I will keep you guys posted.
