Convert from stock FJ20 PTU to PRW-1 or PRW-2?

So my last good button-style power transistor unit on the side of the coil bracket just gave up the ghost, and I doubt I'll be able to find another one in NZ.

I've read elsewhere that people have been able to adapt the 1990s Nissan PRW-1 and PRW-2 transistor units to older Nissans such as the Z31 Fairlady, N12 Pulsar and C31 Laurel which all use a similar stock setup to the FJ20, and since vehicles with PRW units are plentiful in the wrecking yards over here I thought perhaps this might be worth looking into before I bite the bullet and order the super expensive Bosch ignition module that has been mentioned a few times before (a PRW and coil from a wrecker here will only run me about $30.)

So with that said, has anyone attempted this and managed to get it working? Unfortunately there seems to be a lack of wiring diagrams for the previously mentioned conversions.
