He only sells whole kits though. I've got both style input seals at home that have NOK numbers on them that you might be able to cross reference...?
Problem is though, is it that outer seal that is bad, or is it some of the high pressure teflon seals further inside leaking high pressure into the normally lower pressure area?
Somehow my steering box is leaking from the adjuster nut and I rebuilt it again and it still leaks.

I wonder if its cracked...?
