not sure if i posted this in the right bit :-\ but... unusual question i know wiped the windshield washer hose with thinners , and found a faded yellowish stripe on it , like on the head light vacuum hose, never seen this before owned the charger 20 years & looked like it had not been messed a bout with a part from a non matching # engine when i got it . would this be original , or has it been swaped by the 2nd owner years before , didn't even give it a second look when i done the resto .
