First, welcome to OCC......
You can find any/all parts you want to look up by going here....
Cub Cadet Parts Lookup Site.
Type in your 1215 in the second box down and a menu will come up. Please note, there are two different Diagrams based upon the Chassis Serial Number. You will need to know that.
Select the right diagram and you are in business.
