1987 GMC vandura g2500 front door locks

There is a "L" shaped arm with a half moon eye hole in middle. That attaches to the back of the door lock cylinder and is held in place with a special clip.

what is that arm called? and what is that special clip called that holds the arm on new locks do not come with that special clip. I am trying to locate a replacement that can not be acquired from the junk yard, They don't want you tearing their doors open, they want to sell the door whole, lock and all.

Its a part that wears out regularly in the colder states the hole in the middle gets stretched out where it wraps the post on the back of the cylinder.

When its worn enough it won't unlock the door.

every now and then when I try to unlock the door it feels like there is nothing attached to the cylinder post on the back.

I have to pound the lock a couple of times to get it to unlock when turning the key.

So there is something partially broke but not sure exactly where but I know when the door freezes and is hard to unlock,, it can stretch the hole on that arm. Or even break off a portion of the arm.

Google "door rod clip" or "door lock rod clip" . You can find them a Home Depot too. Doorman makes those clips.

Assortment: Dorman #Part # 41017
or

If you have access to a gm parts manual, check groups 10.474 to 10.506 for the part. You might be able to order new parts through the parts department. I know the parts that you make reference to, however, they can be different for different model trucks and years.

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.

the clips are the ones that hold the round rods in place. to the latch etc.
so not sure what you mean by that.

those are definitely not the parts

its a metal "L" bracket that turns counter clockwise and clockwise when turning the key. this arm lifts the mechanism up and down so it is in line with the door button when you push it in to disengage the door latch.

Can they get a part number? Or name?

no which is why I was asking here for what they call that arm.

Someone royally screwed the parts system that auto zone, napa and oriely's uses. so unless you know the correct name or alternate part number. your screwed.

you can not find it on google either. because too many people used the wrong terms too many times and thus google brings up the wrong listings related to it.

when I got that part for the back door at the junk yard. I did not see a stamped number on it.

They won't let me get them from the front doors because they want to sell them whole lock and all.

I don't know anyone with a van so I could take a look or a picture. Have you looked at a suburban barn door? Do they use similar parts?
