One very minor weakness on the W123 is the glove box door. This is because 2 of the key stress points built into the door are made of plastic. One would be the pin holding the latching mechanism ( Kent already has a repair kit for that - see related products. The other is on the lower plastic interior panel that mounts under the two slotted adjusting nuts. Those two lower nuts can be loosened and tightened to adjust the door opening gap. After multiple loosenings and tightening, the plastic in the hole breaks away, allowing the inside panel to become loose.
Product Details
Here is an inside panel with the plastic in the hold broken away.
Here is what it would look like mounted to the dash.
In early 2024, Kent decided it was time to come up with a solution. Almost every W123 is plagued with this problem due to age and usage. Kent decided to custom machine a new collar nut with a locked-in wide washer under the nut that will cover the hole and tighten the plastic liner.
And this is what the two custom nuts look like installed. The washer is big enough to cover the hole, and they "suck" down the plastic tight to the front of the glove box door so the hinge stays tight, the door alignment does not shift, and the panel rattle is eliminated.
The included custom tip screwdriver will allow you to easily remove the original round nuts and install and tight the new hardware after adjusting the door closing gaps.
