Yup. That bearing goes into the larger diameter cut which is typically used by the snout of a converter for an auto trans.
I use the roller bearing in my 4spd 408 setup. So far, no complaints.

i looked at the roller bearing on brewers and its sized for a normal size .75 shaft,

so ill either have to make a sleeve or a stepped bronze bush with a .6 ID

something like that, the 1st step may not be necessary but if i have it on the lathe and the material then why not.

Thanks all for the idea, i didnt even think of using the auto spigot,

ill take some photos tonight of my crank, everyone is super helpful to a youngin`
