Well the project is complete. Overall it was not a terribly difficult process.
Removing the existing Reliable actuator involved disconnecting brake line, reverse shut out wire and the ground wire. Once those were disconnected, taking the actuator off was easy---one bolt.
We had a friend who owns a body shop paint match the new UFP actuator sleeve. We reconnected the brake line, reverse shut out wire and ground. We added brake fluid and then bleed the brakes. Bleeding was probably the toughest--we couldn't get a good seal using the vacuum system so we had to do it the old fashion way.
Please note, the new UFP actuator is longer than the existing Reliable. Safety chains etc., are plenty long for the new set up.
I do like the attachment mechanism better than the Reliable option.
