I bought these dies back in the 70's. I was doing OK and then I broke the decapping rod. This rod is threaded on the end and I believe the collet that holds the decapping pin is also the case mouth expander. I believe the upper part of the rod is threaded @ 10-32. I'm having problems finding a replacement. Does any one know where I can find a replacement or if RCBS made a newer replacement part for it? I emailed RCBS about this and they told me they'll try and answer me in 10 days.
