1967 Upper Radiator (2806066) Hose AC vs Non AC
I don't remember if I saw the typo in the '68 manual before but post #1 had checking my copy to see if what should say "340" actually says "440." It does.
The compressor mandates a curve in the hose. I'm a little surprised Chrysler had two part numbers when one would do. Possibly the straighter hose was so much less expensive they'd save money carrying both. But more likely, I'm over thinking it.
