I have looked on langs website and cannot find the babbits for my rear end. Where would they be located or is their another name for them?
You would be looking for thrust washers.
The thrust washers are now made of bronze (or is it brass). They are generally preferred to the original babbit. I do not know of anyone selling babbit today.
How many should I order - is it two?
Yes - two. You will also likely need some of the steel shims.
So I would need two thrist washer and two steel shims. Will I need a special tool and a gasket set? Anything else you can think of?
