All 8Ns should have 5/8-24 thread. Your plunger is right. The yoke which seems to be 5/8-18 from your picture with a ruler may well have come off of a 52 8N, but if so it would have been replaced at some time. Had a 41 9N here a while back for some minor work, it had the 5/8-18 thread on it, still belonged to the original owner.
Hope this helps.
