Ok so this is a minor issue but thought others would want to know. Other day when putting the top back on I could not get the passenger side latch to close properly. Did some jiggling, took roof panel off back on again and could not get it to latch without extra effort. Took it off again looked it all over and found nothing out of place and it went back on and latched easily as normal. Went to vacuum the interior and found this nipple washer on the passenger seat.

It took awhile but I figured out its a rubber washer on the down post and it had come loose and I had been pinching it in the latch mechanism.

I also noticed when doing an inspection of the roof area that the grommet for the rear roof pin to fit into the car was split.

Went to dealership today and they are ordering new parts for me. Will be an easy fix.

Tom0021 thanks for posting, especially with the picture. So if I fully understand you had the grommet rubber like washer come off of the front latch pin and the split washer is clearly on the back latch pin hole. They are replacing both. Are the remaining ones (driver side front latch and passenger side rear latch pin hole in good shape? Certainly worth checking as we put our top panels on and off.

Yes that is correct the others are in good shape and don't have an issue at this time.

Tom; Those grommets look like good candidate’s for a liberal coating of dielectric grease on the interior faces!
Chip good point and I will be doing that when I grease my seals before winter storage.

Update - it's been a week since I was at the dealership and no call about the parts being in. So I called today and had a good conversation with the service manager.

Turns out that the parts needed he can't figure out the part number for the gasket and washer. He said in the parts explosion it does not show up.

The person he has contacted about the issue has been involved at NCM working on car restorations.

He expects to be on a conference call with him tomorrow and hopefully will get the correct part numbers.

Interesting that these two small parts aren't showing up on a parts list.

Tom; What is embossed on the grommet? You might see if the corresponding C-6 part will fit / work.

It's a 5 digit alpha numeric which is not a proper GM part code, the service manager assumes it's the vendor's part code.

Hopefully I get an answer today.

While not a big issue just starting to get annoying as it should be simple.

Need Some Help Here!

OK fellow forum members now I feel the need for some help. The service manager called this afternoon, still unable to determine proper GM part numbers for the grommet and the washer.

He is still working on it but I am not sure how close he is to determining the answer to the correct part numbers.

Can anyone one here help with this process? See the first post for pictures or let me know if you need further details as to where these are located on the coupe.

Any help here would be greatly appreciated.

Thanks, Tom

Tom; This is going to be a stretch, & a good bit out of the box, but when you have a little time to kill check out a industrial hardware store or a shop that does hyd. / pressurized fluid rebuild / repair work. Have your part in hand and maybe you can find a match. Did you try a Google search for that alpha numeric on the grommet? By the way what is the alpha numeric for it?

On the factory tour I had a chance to talk with a line worker, the one inspecting and installing coupe roofs. He was 3 weeks from retirement and was just going onto a break. He gave me a tip, use Vaseline on the seals and grommets, it's cheap, readily available and won't attack the seal material.

I agree, I have always done this to all my rubber gaskets and seals on my cars, especially my convertible S2000 as I wanted to avoid any drying out and seal issue with rain or washing the car etc. However, I usually do it about once or twice a year, I can't believe that the grommet dried out on a car that is only 4 months old.

I doubt it dried out, that looks like someone forced the alignment pin into the hole while the roof was miss aligned. From my experience that's pretty hard to do unless you are removing or replacing the roof panel with the windows up OR you have one side of the car jacked up (the frame, as stiff as it is, will still torque if one side has more wight on it than the other).

So finally the rubber gasket that goes on the roof panel itself and the grommet that is on the panel just behind the seat finally came in.

From what I can figure out, these might have not had part numbers and as of today a part number does not exist for the grommet as it is part of the panel assembly. I was told by the parts manager that at first he was told that the panel would need to be replaced. He was smart enough to know and hard working enough to pursue getting in just the grommet as replacing the panel was a crazy idea.

The part number for the gasket for the roof panel, pictured above is: 22994154

There is not a part number for the grommet (edited to say grommet) as of yet, the services manager has promised to let me know when a number is assigned.

Above is a picture of the grommet before being replaced.

Hopefully this helps someone for the future.

Hi Tom0021,

Did you ever get the part number for the Grommet? I'm having the same issue with the grommet splitting and mine popped out the other day when removing the roof panel.

Want to drop by dealer to get them to preorder the parts needed, so there is no long wait.

Thanks,

Mike
