AC guinea pig...

I used basically same thing you have pictured, for my compressor bracket i pulled it from a 1986 ramcharger at pull-a-part, had NAPA make my hoses, also pulled the 3 groove pulley off the crank ,only issue was the original 74 alternator was different, so i had to buy a new alternator. The underdash unit on mine is 16 inches wide, and 15 inches deep, it sticks our from under the dash about 4 inches farther than the original ac vents
