Question:

The DICO part number 17550 that you referenced actually matches a fixed coupler that we as Titan Weld-On Coupler part # T1755000.

Most like you have a DICO model 60 actuator though. For a replacement master cylinder on your Dico Model 60 Actuator for drum brakes, you will need part # T4395100. This includes the master cylinder, gasket, orifice connector, hex bolt, lock washer, filler cap and cover. The part # T4745720 is an example of what a Model 60 actuator looks like.
