Bearing retainer sizes

I must be getting senile. I remembered the input shaft gear not clearing the input bearing bore even with the 308 bearing. It's hell to get old.
Nope, the outside diameter of the 308 bearing is slightly larger than the input shaft gear so it goes in the front. Last year I completely rebuilt my tranny and replaced the input shaft. I pulled the shaft from a spare tranny and pulled the 308 bearing and installed the 307 bearing.
