Guess I wasn't clear either. The grommet you have will accept a 'push in' style breather. Some breathers will take PCV on top, so that might be an answer.
edit:but as far as I could tell, Mopar never made a 1" PCV valve.

What I was posted are the PCV grommets that fit the M/T valve cover smooth edged holes. Get those and a typical PCV valve will fit.

I bought my M/Ts new. Each cover originally had two knockouts, one which resulted in a smooth hole for a PCV or breather grommet. The other accepted a 1/4 twist lock breather or fill cap. Hope that makes sense.

In the photo the PCV is in the grommet I posted, the black mopar style breather is in a grommet the same or similar to yours. The chrome breather is a twist lock and was used for filling oil.
