S5 Oversized Stat Gear Bearings?

[JustJeff]

I was at my local Mazda dealership ordering stationary gear bearings for a S5 13B and the parts guy found two different types. Standard and Oversized.

The parts guy did not provide many any hyphens between the numbers so I'm typing them identical to what he gave me.
Standard
082010502B

Oversized
N35010E02 (though I can't read his writing and it might be N350010EO2)

I found that I need standard through surfing Mazdatrix website. Their part numbers are partially reversed but identical other than that.

I expected the dealership's standard bearing to match and I expected the oversized to be the 3 window race bearing. But the part numbers don't match.

I'm just trying to figure out what the oversized bearing is? Obviously I see the N350 in the part number. I'm also looking at the FD bearings that are offered in different thickness. The thinner FD bearings have part numbers 10-E040....very similar to the 10E02 at the end of the oversized part number.
