Hi,
I do not quite understand the quarter tun thing you are speaking of so I thought maybe the 1981 box has a different lock than my 1984 and beyond cars do.
So, I took a look at my 1978 as it has a push in button type. Totally different than later glove boxes.
It’s about one half inch in diameter in the front. You don’t turn any knob.
It is held in by a clip that has a little tiny tab sticking up and out from its own tiny slot.
It looks to me it only locks into its only and only position.
I have never had it out so I don’t even know how to remove that mechanism.
As old as it is, I don’t want to mess with it either.
It might turn out to be that angry dog that’s sleeping.
I ask why did you take it out?
It should have been accessible for a spritz of something, if needed be, to from the latch end.
The others I have see use a clip as you describe but it does not turn either.
It comes off easily as you just slide it outwards from two grooves on the side of the lock cylinder.
The clip should be long enough to engage the side grooves and by continuing to push the clip its should compress down under the grooves.
There is no turning of the clip. The cylinders has a flat or two that engages the door so the lock doesn’t turn either.
The rubber ring rots off the knob but if you don’t mind the ridiculous price for a new rubber they can be purchased.
Personally without the rubber you can get your fingers in deeper to grab the knob but the rubber does seen to make the lock more luxurious looking.
The 1978 only took one finger to open it in the first place! The mechanism is a lot smaller so it doesn’t hit thing inside either.
On the even newer boxes it’s not uncommon for the latch to break it’s on plastic holding bar above the lock.
So bingo!
At first it gets more loose to where it does not always catch or it can let the door rattle.
I have had to replace it with a metal plate to give it something more substantial on one of my cars.
I’m afraid to go inspect the others and see that disappointment coming.
You got hate having to drop the front door down to get at the two bottom screws out too, so you can remove entire box.
On my 1993 I removed the whole dash, this spring, to replace a fan motor and service the wiper shafts so I know where the first frustration can start.
But luckily the 1993 doesn’t have those screws anymore.
The hinge arms have tab that are a bear to undo on the all the boxes.
You have to release the clips, on their right sides, with something really thin but curled on the very end to depress the tabs. Of course it’s plastic down in there and darn hard to see them!
I wish I could see the type latch you have to know the difference.
Just think creatively!
