i know i already posted this question a few weeks ago in the 66 to 70 section but i got no responses so i figured i'd try it here. so i was decoding my fender tag and i have the h51 code which is supposed to mean single air with heater. so forgive me if this is a silly question but what does single air mean is this another way of saying air conditioning or what. i know the heater box that was cobbeled into my car isnt correct so i was wondering what this means also the dash i got with this car (not sure if it goes to it or not) has the billboard style gauges and has 6 vents in it 2 for defrost 2 in the middle and one on each side. car is 69 gtx 440 project got it more or less as just a rolling chassie almost completely gutted so i was just wondering if this was originally an ac car
