O.D. - 3.542"
I.D. - 1.376"
Measured with 6" dial caliper.
Look at this:
http://www.sizes.com/built/ball_bearings.htm
If I read this right a 308 should be 0.906" thick, 3.544" OD, 1.575" bore.
this is what I am finding and it's standard numbers for a 308 bearing , but as snoopy states Timken shows it being narrower which I think is the problem which ebooger ... i think ... stated years ago in an article on rebuilding 833's .
also I think some have a different snap ring groove width .

According to the chart, you are correct.
According to the actual bearing, the chart is wrong.
This is from Timkens website.
This is for a 308LOE bearing and not a 308SG.
Part No: 308LOE
Description Value
Bore (B) Inches 1.378
Bore (B) MM 35
OD (D) Inches 3.5433
OD (D) MM 90
Width (W) Inches 0.7874
Width (W) MM 20
this is the problem , the 308SG is a hybrid and the only other available bearing is this incorrect 308LOE

What is "a premium"? The 6308NRJ that NAPA had (that I asked them to return this morning) was $66. How much worse could it get? 
I found that bearing , in my SKF book , TOO wide as you found out .
I want to say about 80 a pop , but he didn't have alot left , this MIGHT have been 2 summers ago .

Are there different thicknesses of snap rings that retain the bearing on the input shaft? I just measured the bearing surface on an 18 spline input shaft and it was about .800" from the front gear surface to the snap ring groove. This would place the inner bearing race .026" into the snap ring groove.
Snap ring groove is approximately .118" wide. Which would make the .097" snap ring the closest match for my application. Ideally I would need one that is .104" thick to match the bearings I got from Brewers.
The snap ring installed with the original bearing was .091" thick.

We have shims available in .003 .005 and .010 to take up the slack between the bearing/snap ring, as the thicker selective snap rings have fallen victim to NS1 from Ma Mopar. As with the 308 bearings, we have had no luck with having the snap rings made. Best quote was for minimum of 10,000 pieces, and they would NOT mix thicknesses.
