Where to source Saginaw PS pump rotor and vane kit?

Hi all,
Since prices of basic parts and services have gone through the roof. What used to be a $100 outright for a "rebuilt" PS pump for the Holden V6, which most often were only a clean up, maybe a new pressure valve and a seal kit. Now they are asking close to 300 and exchange for just a seal kit run through them (kit costs about $30 so wtf!).
I pulled one completely apart the other day to see if I can easily do it myself, 20min I had it fully disassembled and other than the seals, the only wear parts I see is the rotor and vanes themselves.
I thought, surely. I can do a full overhaul much better than those exchange ones you get for way less and it will literally be like new.
Upon disassembling I noticed the Saginaw logo in the casting so this made it very easy to identify.
However, seems rotor/vane kits are non existent? Surely not. The pump appears to have been very common on most GM cars of this and earlier era including the Corvette. So what gives?
I found this listing which is out of stock for the exact rotor/vane that mine uses, the 2 sets of holes, completely round (although this doesn't seem critical) and has those 3 small identification dimples?
I already have a random seal kit I found in the shed. Would be great if I can get new vanes and rotor as all my PS pumps eventually start to cause a steering shudder and front wheel hop like feeling when flying around a rough corner (100% a PS pump issue despite thinking it was a suspension problem years ago).
The aftermarket pumps they sell now are garbage. Put one on my nephews 4Runner which has the Buick v6 conversion, the pump has basically shit itself after only a few weeks. Noisy as hell and only works intermittently , despite full of clean fluid.
