Air Cleaner lid gasket replacement?

Hey All,

I need to replace the gasket for my 79 CJ7's air cleaner lid...not the smaller gasket at the carburetor, but the large circular deal on top. I've been unable to find it anywhere...any ideas where I can get one?

Air cleaner is the one that fits on the stock Carter 2 barrel. Thanks for your help!

I just used standard weather-stripping from the hardware store.

What I usually did?

Use a screwdriver to dig out the old gasket and any collected crud.

Cut a Popsicle stick down in width until it will fit in the groove, and has shoulders to stop about halfway down.

Squirt in a bead of RTV, then use the modified Popsicle stick to smooth it out.

Let it cure overnight (if you need it more quickly, you can set your oven to "warm" and have it cured through in about an hour. The lowest setting on your oven shouldn't boil water, but will be about twice room temperature.

The RTV can be scraped out of the groove and this repeated as necessary, but I've found that it lasts longer than the typical gasket or foam Wx-strip will - by probably twice. And, it's easier to keep clean, when the bead has been properly smoothed.

Foam backer rod from Lowes / Home Depot fits very close to OEM.

This is what I used on my 83'. It is not an exact fit, but it worked very well.
I have restored a couple of Corvettes over the years and could buy just about any part, I am surprised and disappointed at the lack of after market reproduction parts for the Jeep.

All excellent ideas! Much appreciated!

Is the purpose of the seal to be airtight? I wonder if the Corvette or RTV ideas may be better if that's the purpose...

Yes, you want all the air going in to be filtered. I would use what Matt used ,
