My rear 3rd member has been leaking for years, it is leaking through the threads on the studs. I plan on pulling the axle to fix the leak soon and actually bought new studs a few years ago. I am actually thinking that using a button head screw installed from the inside to use as a more robust stud.

Has anyone done this and has a McMaster PN or specs on the screw? I can figure it out but don't have much free time to go digging before the weekend.

Thanks!
