The firewall side (not being replaced) side has the female terminals.
The terminals, if needing replacement, are closest to
Packard 58 not 56, in most of the cars I've looked at (late 60s). Some call these Ford/Chrsyler terminals.

Get a proper crimper for "open barrel" terminals. Astro-pneumatics is cheap and has interchangable jaws. However the jaws are too wide to fit on OEM and some aftermarket male terminals. The packard crimpers and copies are good but often expensive. American Wire sells and rents these crimpers.
Save the original harness. Its useful for reference and parts.
When the replacement harness on my 67 started to show some issues, I had to replace a few terminals. Some were packard 56. The original harness was 58. So I used the 58, but then the 56 connector was loose. Fortunately I could take the original connector from the original harness and all was good. Small differences, but sometimes important.
