hose from oil breather to air cleaner on 383

OK, the way I used to do it with "twist in" AND I DON'T THINK YOU CAN GET THEM anymore, is to buy a Ferd twist in cap which takes a grommet and hose el in the top. I bought a chrome one like off a Shelby 390, etc

Just like this:

Bear in mind Ma never used these...........Mopar either had the tube sticking up (like the 69RR I pictured) or my 70 had a fair sized grommet in the VC and the breather popped into that. You had to pull the hose off either the breather or air filter to get it apart.
