Progress Thread Project Copper Can

So my headers came in finally the other day and I was able to get most of the hot side installed in the car yesterday. This thing is starting to come together nicely.

So my brain is not functioning right now. I'm trying to figure out how I wanna finish off the hole for the intake piping going through the fender. Firewall grommet? Exhaust trim ring? Help me out here guys can't find any clear pics of the passageway. @84Ttop @TOOLOW91 @srtthis @RacEoHolic330 any of yous guys know some slick tricks?
If you're referring to the hole in the apron where the pipe goes into the fender well - I have vaccum hose that I split down the middle and put around the edges to finish it off and keep the pipe from getting marred up by it and finish off the edge .
