Hello Bill,
I have been looking at my stash of build sheets trying to come up with the differences in hoses. (Mine is at the office so I don’t have access to it right now.) One example I have is for a 440 4bbl. Cuda built November 21st. It shows the “inlet hose” as being a #65 on the build sheet. It is an A/C car. I can’t even find a reference for that hose code. Any help with that one?
