AC HOSE ID

I have 2 NOS AC hoses that I am trying to identify.
I felt this would be the best place to find out since the restoration guys hang out here.
The first hose has GY 13/32 FREON 4755 2667 stamped on it and is 28" long overall.
I am thinking that the 4755 is the vendor code and 2667 is the 266th day of 1967 date code?
The second hose with the muffler has GY 13/32 4769 3286 stamped on it and is 36" long overall.
I am thinking this one has a 4769 vendor code and 328th day of 1966 date code?
The hard part is finding out what they fit and or a part number.
I have seen similar hoses for both but not exact and need your help.
Thanks! John

I don’t recall ever seeing any ribbed hose like that on 66-67 cars. Look on the steel crimped portion on one end and you will see the part number stamped. Those could be 76 and 77 hose which is what I suspect.

fastmark,
Thanks for your quick reply and information!
I have checked both hoses and only the short one has something stamped into fittings.
The short one is stamped HP9860 on both ends.
Does this match up with a Mopar part number?
Thanks! John

Im thinking late 70s ,,,maybe even late 80s vehicles.The ribbed carcass hose was NOT seen on anything up to at least mid 70s

Find someone with a Diplomat or Volare parts book

Thanks gtx6970!
I started looking at pictures of 1977 Mopars with air that have a similar hose for the one dated 3286.
I found a 1977 Cordoba big block 400 car with the same hose coming off the compressor with the muffler.
So that one is solved!
I am still looking at 1978 Mopars trying to find the 2667 dated hose.
Thanks! John
