You can look at Sprague as well. But for any cap of that size, you need to be aware there may be a need to discharge them prior to placing in the circuit.
The resultant stored voltage can damage other electronics in the circuit. They sometimes recharge all by themselves after being drained.

Hi Chris,

When I think of specialty capacitors, the first vendor that comes to mind
is Cornell Dubilier. Have you checked with them?
