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
