Expert Reply:
If your drums are 4 inches wide where the brake shoe pad makes contact with the inside of the drum then you will need 12-1/4 by 4 inch brakes # 23-438 for the left and # 23-439 for the right.
If you are measuring the overall depth of the drum then you likely need the 12-1/4 by 3-3/8 assemblies such as # AKEBRK-10L which would fit on Dexter axles.
