This is what you need on the valve cover elbows and tee inlets. Your Dodge dealer should be able to get them.
Single Bond Nylon Hose Clamp 11/32.
Do not automatically order this size - the link is for reference only. I will have to confirm what I ordered if the dealer can't get them for you.
Here's my catch can setup. I moved the tee over to the center using 1/2" nylon air brake tubing that I shaped with a heat gun. I installed a catch can on the shock tower strut, then plumbed the outlet to the air box.
I checked it after the first and second track days at Road America this past weekend and there wasn't much oil in it. But, I was still having the same old oil smoke and exterior seepage problem that has plagued my car on big, fast, heavy braking zone tracks since it was almost new. I believe it has more to do with PCV flow control than valve cover venting. I have to wait until my car gets back next weekend to begin a new sleuthing adventure to determine the source and effect a solution.
