I will settle for a smaller 10" un-silenced air breather from a 1966 /6 charger 225 as the larger ones are crazy $$$ even these small ones fetch some $$ I got this on on moparts for 15 bux

I will swap on my 68 VC on so the push on oil cap I got with the air breather will hook up to it. I like old and retro look of it.
