[T3] Rear Wheel Bearing Cover

[Brent Bottolfson]

One of my IRS rear wheel bearing covers is a bit damaged on the inside 
where the grease seal fits.  The outer bearing on the same side has 
obviously been replaced at some point as the roller retainer is different.

Are all of the IRS bearing covers the same?  Looking at pictures of 
others, they don't appear to have exactly the same casting.

Is this one safe to use?

Here's a couple photos:
