There were some 3/8" brass (copper alloy!) machine screws on ebay for $0.20 each (and that includes the cost of shipping)! They are used to electrically connect the capacitors to B+ and B-. It's sort of hard to explain. You would need to see a schematic. All 500 amps (or whatever) needs to go through those bolts to complete the circuit.

I got enough for 10 or 11 controllers (116)! And they were new too. Without the cost of shipping, from, they are $1.63 each! The cost of an open source motor controller just dropped by $15.73.
