Lower control arm pin

They are pressed in though. Don’t think it would come off

Which poly bushings are you using?

Typically a full on press isn’t necessary to slide the bushing onto or off of the pivot shaft. Cue all the knuckleheads saying that the rubber in the rubber bushing somehow locates the control arm.

Usually with poly you can slide the LCA and bushing off the pin. You can install the pins and then slide the bushing and LCA onto the pin already installed in the K. It should require some effort, but not a press.

I thought we were talking about "POLY" bushings here?
Then you are right, if you're using bushings that press into the LCA.
It won't work.

It’s clearly a poly bushing in the picture. Some are a tighter fit than others though, and not all of them are constructed the same.

Starting to think it’s not worth the price. Stock worked for 50 years, maybe I shoulda stuck with it. Oh well.

Stock didn’t work for 50 years, not with a single bushing. And certainly none of the rubber reproduction bushings will last anywhere near that long.

Looks like you already did the right thing and have greaseable pins. The installation of the poly bushings is a little different, it will work fine but the process is a little different than with rubber. Poly is not rubber, the install is not exactly the same. In fact, if you do the install the same as with rubber, you’ve done it wrong.
