Metric Mind supplied two Schaltbau 162 contactors in a box with a precharge circuit.
The Arc Chamber comes off fairly easily after unscrewing the nylon screw in the top of the contactor. The arc chamber must be removed to change the cables.
Unfortunately the box doesn't fit at the front of the car, so I will have to repack them and the precharge circuit, or replace with another contactor. Likely suspects are the Gigavac GX14 or the Kilovac EV200
