Greetings Mason - welcome.
One source might be Surplus Sales of Nebraska:
(CFC) HT580200-75 200 pF 7.5 kv 6.9 amps $21.00
(CFC) HT570200-15 200 pF 15 kv 15 amps $42.00
depends on just how QRO you'll be.
Note that these are 'doorknobs' - if your currents/peak voltages are
less, then there are cheaper mica caps that might serve.

Good ol' Johnson roller inductor.
Ceramic. Silver. The real McCoy. Only a few available." $175 (OUCH!!!)
Nice ceramic core roller inductor. Shaft end has slot to mate with nylon
quick coupling (shown below) which fits 1/2" shaft. Stand alone frame was
removed from IRV-503178 tuners. Little or no previous use." $99 (oww...)
