Sorry to hear about that Tyler, but to answer your question - if your current cap # 3876 measures 1 1/2" wide overall and has a 1 1/4" thread diameter then yes both the Replacement Master Cylinder Cap with Diaphragm for Dexter Model 10 and 20 Brake Actuators # T4830601 & Replacement Master Cylinder Filler Cap for Dexter Model 60 and Aero 7500 Actuators # T4480701 could work.
