Anyone know how to get inside one of these old mic connectors?

So I got this cool Aiwa omni dynamic HiZ mic at a pawnshop during a road trip. Sounds cool but the cable is super short (4ft) and annoyingly stiff. I wanna make a longer nicer cable but I can't figure out how to get inside the mic-end connector to the solder connections. The set screw seems to only release the strain relief spring. I tried pushing out the brown phenolic disk from the rear.

Looks like a Switchcraft 2501F, which are still available. I'd just buy another one but the price at Digikey is almost $40 (CAD). I've seen as low as USD15 but thats still stupid and I'd get dinged for shipping and brokerage fees crossing the boarder making it not much better. The part is AKA Amphenol 8075MC1F or Heathkit 432-1 (both disco'ed) and was popular for unbalanced mic connections on NAmerican PA amps (schools etc vs music venues), like my old Bogen (switched them out for 1/4" and modded for guitar). The one thing that would be good about buying a new one is that I assume it will be more obvious how to get in there to solde rthe wires on - perhaps this is the stock AIWA cable and it wasn't meant to be messed with (like a molded 1/4" today).

Anyway this is the mic:

If you screw that grub screw on the side of the connector into the connector shell so that it is fully inside the exterior, the shell may then slip off downwards.
