QUote:
"I know they thread in with some difficulty ..."

Somewhat begs the question as to whether or not the NEW stud was delveloped with an interference fit thread for LOCKING purposes rather than leakage.

My 1948 2262 has a THIN flat washer under the NUTS. Only about 1/16 inch thick is the washer. So i assume it is NOT a HARDENED washer. But then again i don't know if my washers are OEM or not, I'm guessing they are.

So one mite need to study NUT washer differences between those used on OLD studs and washers used on NEW studs. If the OLD stud washers were THICK HARDENED steel and NEW stud washers thin and therefore not hardened then the interference fit of thread would be for locking purpose and not leakage.
