How to use this chart:

Depending on the damage or the diameter of your bore after you cut or remove the old sleeve, you may need an oversize sleeve.

Understand that the all the models on the left before the blank divider will take the part numbers on the right depending on what size OD sleeve you need to make the repair correctly.
