Down the power steering shaft seal rabbit hole
Installing a power steering pump in the zombie, figured I'd re-seal it just for S's & G's. Bought a reseal kit from Rennbay, take the pump apart, clean everything up. The mother in law is trying to talk at me while I'm trying to tap the new shaft seal into the housing, so of course I get it a little cockeyed and now it looks buggered:
Dumbass. (The MIL, that is....)
The seal in the Rennbay kit is a KOK PS-39040, N257C. No amount of Googling reveals a source or specs on these numbers.
Original 1989 PS pump shaft seal:
FWIW, the power steering shaft is 19 mm:
With a little internet jockeying, I think this is made by Simrit. BASL is a particular cross section:
I assume that 33.33 is the OD, 19.05 is the shaft opening, and 7.93 is the width, since that's about what this seal measures.
Bottom line is I can't find a source or a cross-reference for either of these.
Simrit's parts catalog goes from 32x19x7 to 35x19x8, skipping right over 33.33 mm OD..
Anyone got a source so I don't have the pleasure of spending $25 for a single shaft seal?

I literally just did this aswell, its $15 for the kit on pelican, and when you put the seal in, i recommend using a piece of wood or something broad and flat to tap it in, one edge likes to pop up everytime you hit the other. Incase anyone else was interested, i went off this video of a 944 pump, its exactly the same internally:

So I think this might be a metric seal based on the US-metric standard of 25.4 mm...
Maybe try searching for a seal for a 3/4" shaft with a 1-5/16" OD?

Okay, with that clarification,
So TB is the equivalent of Simrit's European BASL design. I'd guess one of these would work, probably the ones made out of NBR.
Of course, any cross-reference site leads you to an e-mail address to inquire about purchasing large lots of these.....
EDIT: BD1295-E0 cross references to SKF 7475. Will order one see how they match up.
Code:
Part Number Style Material Shalt Bore Width BD1295-E0 TB NBR 0.750 1.311 0.311 BPP301-A0 TB ACM 0.750 1.318 0.311 AP0921-E0 TB ACM 0.750 1.318 0.311 AD0921-E1 TB NBR 0.750 1.318 0.311

It's thinner, 6.35mm vs. 7.68, but the ID/OD are correct.
Just push it in with a block so the outer face is flush, with a catch-pan under
