They aren't using factory kits.
They are using the original parts within the PowerMaster and replacing all the orings. If you spent the time and figured out the correct sizes of all the different seals in the P/M you could rebuild yours too. Then you need to make sure you have the orings of the correct material so the brake fluid won't counteract with it and destroy the new rings.
The factory kits came with new orings and some replacement parts.
So I should correct my earlier statement.
The factory rebuild kits have been discontinued for some time.

There are two types of replacement parts commonly used:
OEM (Original Equipment Manufacturer)
OERP (Original Equipment Replacement Part)
The only real difference in the two is the box they came in. Same quality and spec (At least they are supposed to be)
If someone is rebuilding them, someone MUST be making parts to rebuild them. GM may have discontinued the OEM parts, but that doesnt make them unavailable in the aftermarket.
Kirban sells the PM grommets...seals the reservoir to the MC...as for the MC rebuild kits...as stated no longer available but there is a place that sells the internal MC O-rings...the price is outrageous though...think it may be Cardone...no one sells the other internal MC pieces like the power piston replacement that the GM rebuild kits had...but you really don't need to replace that piece...
That would depend on the condition of the core though... I have units that have been stored for years, but shipping them to CONUS is just too costly...
it isnt worth it for me to ship them to get the credit... unless I find a cheaper shipper....
For the parts... I rings, for the MC, and parts for the pump would be the next failure... I found a place on line that does remans of the PM... I should email and ask about parts... no doubt some other vehicle uses the same seals...

It’s been a couple years. But do you have the part number?

Richard Clark's Garage will sell you an O-ring kit which you can use to do the job at home. New switches are readily available and new accumulator balls are too. Those items are the minimum for a rebuild. Seals, switch, ball.
The pump & motor assembly is NOT available new. If yours is overheated or otherwise toast, then you are pretty much converting to vacuum. And vacuum is pretty good until you try to hold the car on the starting line and build some boost. But that's not a huge deal.

I think you just ruled out Kirbans..lol
Follow Beatav8’s advise and DIY or swap to vacuum.
