This isn’t true. Might not be around anymore, might not be able to buy only one, but they were out there years ago when I searched. However...Not the way I went, not the way I would go. I think it’s sad that the suppliers are raping us on cost for parts, wont warranty it at the outrageous price, but if it’s that important to your piece of mind, give up the coin.
I would like to see pelican source a double row solution, rather then single row with spacer, but doubt that will happen. Their solution is fairly priced but becomes a maintenance item. As easy as pulling the tranny is, not a terrible compromise.

Well, last time I looked around to find a replacement for mine in the same exact size, I could not find it from any brand. It`s a special size manufactured for Porsche by NSK. It also has a groove for the spring clip that is not common on bearings, or at least not where it is on the outer ring. A bearing like this could only be used in the Porsche IMS, nowhere else. Maybe it was available in the past, but not anymore, or at least I couldn`t find it. I assume the one you remember of was the original NSK? As far as I know Porsche sells the entire IMS and not the bearing separately.
