D353 engine thrust bearing.

We had excessive thrust play in out 9h d353.
We pulled the engine to find the thrust face to the rear of the crank chewed up.
The bearing is a 1n4335 that's stamped also with 5nedn unan 0.63 os 0.63 us
From what I found this bearing is listed as a 25 over 25 under or is it a 63 over/under?

Do they make oversized thrust bearings or should we be looking for a crank?
Is it possible to have the crank welded up and ground back to spec on the one thrust face?
I'll be calling a bunch of crank...
