Changes to wheel hubs

[Jacques Reed]

The sling caps are held on by the three studs part No. C 380304-S which are 1/2" dia with 1/2 UNF and 1/2 UNC threads either end. My NOS hubs shown have these drilled and tapped holes.

The front hubs on mine have both the small, tapped holes for the standard cap and the larger holes for the sling cap studs. One size fits all as often is the case so perhaps some late war trucks had either cap, or it was just to keep parts inventory down.

I put 1/2-13 UNC grub screws with Permatex into mine to seal the stud holes as my earlier truck should have the standard caps.

Cheers,
