Hi Darryl
In post 308 you asked if anybody knew the difference between -2 and -3 UN threads.
I only noticed the question today and had a look in a copy of Machinery's Handbook 1971
To put it simply the differences are to do with production and not maintenance. The numbers designate the class of thread in relation to manufacturing tolerances and should be compatible.
In relation to the axle flange collets, I can't guarantee that they are the same but the Studebaker US6 used those which probably means they were also used on the split diff GMC 6x6. Ross Prince may have them.

According to the GMC SNL, collets are used on the rear axle drive flanges. They are referred to as dowels and the Timken Detroit part number is TD-1246-X-232 General Motors part Number is GM-2124231
