68 7/16 wheel stud knurl size
 

I need to order new lugs for the rear of my 68 the originals are just to short for my liking with the new wheels . The fronts are fine since I replaced the drums with rotors . The stock appear to be 1 1/2 inch long under the head . I’m looking at these from Dorman . I haven’t removed a stud yet to measure but I’m sure someone here knows the diameter of the stock knurl . The ones I’m looking at have a .475 in. Knurl and are 1 3/4 inch from under the head .

These are what I’m looking at

I also thought about just using these wheel lug nuts in order to get more threads engaged.

Same stud front and rear with factory drum brakes My Dorman book is listing a 610-186 part number. Specs are 7/16-20, .472 knurl 1-1/2'' long and a shoulder of 11/32''.. Personally I'd keep the stock wheel studs and go with the lug nuts

I’ll try the lug nuts if they don’t work I can always change the studs later. Not like I’m using the truck in winter

Those extended type nuts don’t work on stock rims.

I know I have US Mags slots on the truck
