I am wondering if the number you found on the old one is actually 05680-C and not 05680-0. The reason I say this is because there is a Demco master cylinder marked 05680-C. Which would make the Demco Actuator Replacement Master Cylinder # 5650 the correct replacement part.
The Demco Actuator Replacement Master Cylinder # 5650 fits all Demco drum brake actuators and is likely what you have.

The Optronics # BUL602CRB is a 2-function lamp, taillight and back up lamp so it won't function in the fashion you're wanting. The good news is that we have a grommet mount lamp that will provide stop/turn, taillight and back up lamp functions, part # STL211RB. If the existing lamp is a 6-1/2 x 2-1/2, this would make a great replacement. If the lamp has been in place for a number of years, you'll want to replace the grommet as well. We offer them as part # A70GB.
