Default Door Ajar part

I need to find a replacement for the plastic part that comes in contact with the 'door ajar switch'. The part is (maybe) 3/4" square. Its not the metal piece with the holes which goes behind the switch. The part I'm looking for touches the tip of the switch to turn out the door ajar light on the dash. I probably could fabricate something, but I wanted to see if anyone has seen it online.

Hi ntd,
How about these?
You can find something quite similar in the hardware section of your home store.

Alan

Thanks, Alan. That looks like them. Funny, none of the Vette parts sell them. Do you know if yours have a peel off adhesive back, or do they need epoxy to attach?

Hi ntd,
All the replacements I see have some sort of pressure sensitive adhesive on them.
It looks to me like the original bumper pads do too.
Regards,
Alan

I have bought some at one of the Corvette parts places before. I think it it was Corvette Central, but they are not here to find.

Based on Alan's suggestion, I bought a pack of these at the local hardware store. Look like they should work. Hope to turn off the Door Ajar light! Thanks to all.

Suggest you use some 3m or weatherstrip adhesive that peel and stick wont hold and one day your light will be back on and one of your pads missing.

Alan may know better, but my understanding is that these cars did not come equipped with them, you are supposed to be able to adjust the switches and make them work!

Here are photos of a black dense foam pad from my 1-owner '70. The pad is 7/8" square on the adhesive side, and just under 7/16" thick, although it could have been thicker 47 years ago.

Hi,
It's difficult to know if all cars had the pads or not.
There also seems to be variation in how the pads were attached.
Cars are seen with the remains of 'psa' and others are seen with adhesive smears.

Yellow 70….I'm surprised to see the use of the square dense foam pad at that location… I thought those pads were only used as cushions for the rear window tray and were located on the underside of the rear deck below the window.
???
Regards,
Alan

These are 2 original 'foam pads'. They're larger than the pads typically seen used on the door.
The round indentation is from the pad being squeezed against one of the rivets used to assemble the tray.

Based on cars I've seen and judged, these rubber blocks were used by the factory on an "as needed" basis. Body variation sometimes required the block as a spacer to maintain a firm engagement between the body and the plunger switch. Sometimes there's just not enough thread length in the switch to make the needed adjustment.

BTW, because I have a convertible, I look at a lot of these. Never seen anything but the rubber ones, similar to those sold by the restoration houses. Also, I've never seen one with anything but PSA adhesion.

Hope this helps.

Alan ... I also have the rear window tray cushions. They are a slightly larger cube, whereas my switch pad tapers, similar to the Zip product. You may see in my first photo the indentation made by the switch plunger, and I'm sure it was adhered to the door.

Hi 70,
That's interesting!
I'm still surprised to see that foam pad used at that location on the door… but it's certainly possible.
Regards,
Alan

On my 71 there were those 2 foam pads I showed, and single thicker version of those pads, but of about the same size, located so it hit the middle of the tray.

The main issue is to not use a pad that is too thick. If you do, it will damage the switch when the door is closed. That pad just needs to make contact with the pad and move the switch about 1/8". You might use some clay or Play-Doh to assess the gap immediately adjacent to that switch when the door is closed. Use the thickness measurement on the clay to calculate the thickness of contact pad you need, so that you don't have excess travel on the switch post.
