I'm working on something similar -- going from 1964 through about 1989/1990 (possibly beyond depending on how it goes). Although I only completed 2 books of that run so far. It appears I'll be doing them through H&R and would like to use your dies, if possible.

Absolutely -- they have both dies and anyone can use them.  I'd be interested in to share maps of the 1980s if you want to compare.
