I'm trying to put a 2,599,xxx Garandicon back to stock parts. I need a -12 S-A1 heat lot bolt.

When (if) I replace the bolt, will it affect the headspacing or are they uniform enough that it should be OK?

I'll check the headspace anyway for safety, but if I will probably need to re-headspace the rifle, I probably won't get the bolt.
