Wheel stud replacement question

[NewToThis66]

I am replacing the wheel studs on my 66 GMC so i can add wheel spacers for my new rims to fit. Is there somewhere that has a comprehensive chart of wheel studs?
I pulled one of my current studs and measured it:
Under head length - 1.3 (new ones need to be 1.8)
Knurl Diameter - .554
Shoulder length - .46
Thread is 7/16 - 20 currently (would like to stay the same if at all possible

For my new ones i can cut them down to match the 1.8 that i need.

The closest thing i can find to what i need is the Moroso #46160 but the Shoulder length seems to be significantly shorter than my current ones. Does this matter?

Dorman parts is the supplier of these parts. Most parts stores have size catalogs but you might find it on the web.

Check a mid 60's Corvette. We used to sell a lot of these at the dealership for guys putting mags on their cars but can't remember if they are 1/2" longer or not
