just got my crewcab back from paint, went to lock it up and the rear door lock rod fell down the door.
when i fished the door lock rod out, also found this other rod laying in the bottom

i have taken these doors apart a few times, but have never had to screw with the lock rods.
as you can see, there is jack for access on the rear doors. i took the door handle out and tried to use a mirror and flashlight, but i can't make out a thing. tried to see how the other door is, but can't see nothing on it either.
looked all over online but can't find a diagram or anything about them.
was trying to avoid taking it completely apart again as i just put new window run, fuzzies, and 3/4 window seals in it.
anybody know how or where the big rod goes? the door lock rod seems to clip into a plate with a rod connected to the latch. thanks

That looks like the interior door latch rod . But could be the power door lock rod , separate from the manual door lock rod . Is that the original door ?

Is that the door in question in your last pic ? If so it is prolly the power lock accuator rod.

If you dont have power locks , that rod would be better off in the garbage instead of rattling around making noise for the rest of your life .......lol

ya, that is the door, and no, it's not the orig door.
it came from a '77 sub with manual winda's and locks.
i welded up the body trim holes quite a few yrs ago and stuck that fatmat all over the inside and out....don't recall the big rod being in there....
i have been trying to find a diagram or exploded view of a crew or sub rear door, but no luck
can't lock the rear door

I have an open rear power door . I will check it out

You may have to find a junk rear door for cheap and disect it

Ok , looks like your short rod with door lock knob connects to a pivoting bracket. The long horizontal rod in your picture of the door is also conected to this pivoting bracket . On the other end of this long rod is another pivoting bracket . This bracket is located above your door latch assembly but not attached to it . This is where your mystery rod i believe attaches. It connects on one end of the pivoting bracket and runs down vertically and attaches to the door latch assembly. The difference i see between power and manual is the length of your mystery rod . On power that rod is longer . It runs past the door latch assembly and connects to a power accuator below in the door . A bracket attachement mid way at the latch assembly is then connected to this longer power window rod . This is where it appears your manual lock rod would end and attatch to the latch assembly. I dont know if i can get pics . Its tight
