I buggered up the threads on the adjuster screw on an older model Dillon bullet seating die. Although the die still works fine, the fine adjustment has been effected adversely. I'd like to purchase a replacement part for this one single piece.

I'm not familiar with what Dillon can do in this case.
• Are individual die parts sold?
• Are die repair parts still available for the older design dies?

The part is a 9mm bullet seating adjuster screw, the part with the male 5/8-24 thread.

Please advise.
