Having trouble finding the right parts KZ750 E3

I bought this bike as a project to keep busy but I'm having a hard time finding the right parts. Seems two spark plug connectors are completely missing. Looks like one of the ends even broke of in the ignition coil.

The ribbed compression boots wouldn't have been a separate part, so you'll have to get the missing stuff from a used coil. there are o-rings & washers to give a waterproof fit for the spark plug wires. I installed new green Dyna 3.0 ohm coils & spark plug wire set
