JEFF: Hi, I'm Jeff.
JONATHAN: And I'm Jonathon. We're with LateModelRestoration.com. Today we're going to be talking about power door lock actuators for your '79 to '93 Fox Mustang. Our 50 resto door lock actuators are available individually with the attaching rivet, or as a pair with attaching rivets, door panel push pins, and the door panel removal tool.
Now, one special feature about these door lock actuators is an NPR rubber boot. This is exclusive to 50 resto. This boot will not degrade, and will not allow water to penetrate the actuator, which is the main problem that plagues other aftermarket lock actuators. Now Jeff, tell me a little bit about the tools we're going to need for this install.
JEFF: Sure thing, Jonathan. You're going to need a good hammer and a drift, a drill, two drill bits, a 3/8" and a 1/4" drill bit. Lastly, you need to pick up a good large rivet gun, which we do sell on our website if you need one. Now Jonathan, is there anything else I need to know or can we get this install started?
JONATHAN: Let's get started, Jeff.
JEFF: All right.
JONATHAN: The first step in getting your power door lock actuator ready to go is selecting which shaft you need. You'll need the small, "s" shaped one-- you can throw the rest of them away. Simply slide it into the actuator and set the pin with a hammer. Next thing, you'll notice you may have a little bit of casting flash here on the rivet hole. You may want to go ahead and take your 1/4" drill bit and enlarge that hole, that way the rivet passes through. And now we're ready to go pull the old one off.
As you can see, we've already got the door panel removed. If you need help with that, check out our door panel removal video on our YouTube channel. Now the first step in removing your door lock actuator is grab your drift and hammer and knock the mandrel of the existing rivet through. Then you grab your drill and your 3/8" drill bit and drill through the head of the rivet. Drills through only the head, don't go any further.
Your existing door lock actuator is going to be in the door just like this-- has the same rod on it. It's really hard to get the shot in the door, but I wanted to show you the motion to get it out. Basically lift it up and pull it out, and then you can unplug it.
As you can see, that boot is completely disintegrated. And that's why this lock actuator failed-- water intrusion. Now you can go ahead and plug in your new door lock actuator, slide it into place, and we're ready to install the rivet.
Once you get your new door lock actuator hung on the door latch and plugged in, grab your new rivet, engage it into the back of the actuator, grab your rivet gun and set your rivet.
JEFF: Alright, Jonathan, it looks like it's functioning properly.
JONATHAN: Yeah, man, it's working great. All I go to do is throw the door panel back on and we're done with this install.
JEFF: Man, I sure do appreciate the help today.
JONATHAN: Not a problem, man.
