A833 O/D gears in an A833 1:1 ?

I built two A body 4 speeds using the aluminum overdrive case, side cover and extension housings for my '73 Duster I had. From cast iron case, side cover and X housing to aluminum, the weight difference was 41 pounds. The overdrive cluster pin is slightly shorter due to the plug in the front of the aluminum OD case, no problem with 4 speed guts. The first one I built I used the guts from a B body Hemi trans, but the shorter A body mainshaft and X housing. The other was a 23 spline. No difference in the pin diameter.

As far as which bearing to use, just use the bearing that fits the hole opening for the outside diameter. Big bearing case? Use the 308 sg8 bearing. The width and inside diameter is the same as the 307, but not the same as a standard 308 bearing. Same with the X housing.
