Maybe I missed something, do you have an old stud to measure? How thick are the wheel flange, brake drum and wheel? What size is the hole the knurl fits in?
NAPA has a book with studs in it with life size pictures and all the dimensions. Same thing for the nuts. They seem to have several lengths for a given thread size and knurl. I have never seen any of that on line.
I found 1/2" studs to replace the 7/16" originals on my '62 K10 when I put disc brakes on it, right out of their book. Same thing when I put metric studs in my trailer to match my 2000 Silverado.
