I'm detailing my 71 Challenger 340 during the cold weather and have a question of some hoses. I'll post pics of the hoses I have questions about. The first hose goes from the shaker baseplate to the breather on the valve cover and is 5/8" diameter nipple size. It has numbers on it that read as follows. The first few numbers are illegible but the rest read 904 90142A 2660 as seen in the picture. The second picture shows the hose has ribs on it. Anyone know what the entire should read? The hose isn't cracked but is original and doesn't show well. Any really accurate repros out there? Thanks.
