I just replaced my air cleaner rubber mounts because my air cleaner was shaking around and loose. 84 300D. The mounts which were on there bolted to the air cleaner but had no bolt on the bottom to attach to the support bracket. They just had flat rubber bottoms with an indentation, and they just rested on the bracket. I was always able to lift it up off of the bracket. The new ones I ordered screw into the support bracket and then bolt onto the air cleaner. It is much more solid now. (I also ordered the heat shields, which were missing.)

Has anyone else seen these rubber mounts that just rest on the bracket? I am thinking that maybe the PO found these generic mounts somewhere and used them instead of getting the correct part.

The rubber mounts, should have a threaded "rod" (bolt) on both ends. One end threads into the intake, the other thru the air cleaner with a nut securing it.

Give your new mounts a few years, or maybe months and they will miraculously turn into the generic type you found on the air cleaner. The upper or lower attachment will break off and the result often looks like the part is made to attach on one side only.

My new ones have a threaded rod on both ends, only the rubber is hexagonal to allow getting a wrench on it. I thought that was a nice feature.

The both work. I believe that the hexagonal ones are a bit shorter. I prefer hexagonal ones because you can get a wrench on them.

Yes, I have seen lots of the rubber mounts that just rest on the the bracket. They are called "broken mounts" and have to be replaced with new mounts.
