I bought the Novak intermediate shaft and bearing kit....the bearings appear to be the same as you get with any intermediate shaft kit.
The shaft is nice. It's cut for "O" rings to seal at each end....however it is really difficult to install without cutting/slicing/ruining the "O" rings....
I put the one I got from Herm back in and it's fine....
I got both my transmission and TC rebuild kits from Herm....
