I suggested 10W wirewounds because I simply don't know the ratings in
watts
of the "official" HP resistors. Tony Smith's 5W suggestion a few posts
back will
most likely work perfectly well. 0.022 ohm, rather than 0.025 ohm, will
make
no practical difference.
The originals are plug-in jobs, so you may have to find two bits of brass
to stick
down the sockets, and solder the resistor(s) between them. The aluminium
chassis under KB boards prevents you soldering one on the underside.

I've had a quick look, and they are 5W resistors (size determines power).
You can unsolder the original; the pins are hollow so just heat them up with
the soldering and pull on the resistor, they'll come out easily enough.
It's occurred to me that 0.022 ohm is rather smaller, and it seems these are
a rather special resistor.
The smallest you'll be able to get without any major effort (i.e. beyond
wandering into a Jaycar store) would be 0.1 ohms, as per here:
. As Andy suggested
before get 4 of those and solder them together. Looking in the case
arranging them in a 2x2 formation might be the go.
Total cost will be $1.60 plus a bit of soldering.
I'm not surprised you can't get them locally, none of the sellers want to
stock spare parts to cater for the 6 of us who own these lathes here in Oz.
We should track down the other 4 and start a club or something.
