Lowes have them for delivery!! Home Depot seems to be down here in UK this morning
Im sure some specialists would have them cheaper for mail order
When I am in the US on business I try and visit Home Dept and/or Lowes and have been surprised in recent visits about the availability of Metric parts and tools to the extent of buying some small sized long reach Metric sockets at a very good price, as well as small US screws for Drake kit and the like

Actually, Adrian, I'm glad I didn't buy one of those, because finding
short M5 metric screws here in the back-country of the USA would have
been a real challenge 8-D

I did resolve the problem I'd been having with my 8410. From time to
time, it would seem to fault; the HV would drop to zero after a few
seconds, and if you were watching when it happened, you'd notice the
plate current LEDS suddenly lite all the way to 1.5A before dropping
to zero. The curious thing to me was the LEDs would remain lit up;
yet, there was never a Fault LED. The blower would shut off
completely. This happened before I connected the amplifier to my
computer, so the amplifier was NOT getting power for the LEDs from my
USB line.
After awhile, I got around to examining things carefully, and finally
found this:
I wound up replacing those with six paralleled 1000 pF/10 kV discs,
spread out so they wouldn't arc to one another, and the amplifier has
been working fine since. I suspect the caps were blown due to
high-SWR events, one at a time. I was very surprised to find only six
kilovolt discs being used where the plate voltage was already half
the voltage rating of the cap leaving little margin for "mistakes".
