CB99SS

I've got a moser 9" in my 99 SS. I'm in the process of changing out the gears and I've noticed the axle press ring is hitting the inner axle seal. I'm running their bearing kit 9508B which is the sealed bearing with an o-ring. I did a search and found the national seal 15141 but that seal is wider than the original seal so the issue will be worse.

Has anyone had this issue and what did you do to fix the problem?

Thanks
Chris
