Slick 60's

Might have to pull it to get dimensions
Any bearing store should be able to get a seal to fit
If the shaft has a groove ... polish it up with emery cloth
Even if you can’t polish it away, just smoothing it out & a new seal
Should work good for a long time

if your tranny has a slip yoke like mine, its a good idea to replace the bushing while you are it, or the new seal may not last long.
