Do you have swing tower bushings to match these Cat backhoe pins?

Yes, Broken Tractor carries matching bushings for the swing tower area on 416D, 420D, and 430D backhoes. These include the Boom Bushing at Swing Tower (SKU 237-2252), the Outside Bottom Swing Tower Bushing (SKU 237-0944), and the Bottom Swing Tower Inside Bushing (SKU 237-0945).
