Breather Hose - 273 HP CAP

I’ll look for pictures, My dad 66 273 Commando with the CAP package with the factory original hose, the hose has some ribs on it I believe but not all the way around, there are some small sections between the ribs where it is smooth, not sure where you ever find one like it unless you got lucky with a NOS one... The CAP chrome lids are pretty rare And the correct house is even harder to find
