Reply to "Heater core - keeping it cozy"

Good idea. Fresh air is nice if/when the A/C goes out. Early '71 and later '74s had a stock fresh air option with different controls, routed thru the heater boxes. I ran two such cowl holes to big 90 degree copper fittings with home-made throttle valves aimed at the seats (no hoses needed). They were very effective crossing the Mojave desert, as my A/C never made it to and from 'Vegas while operating! Cracking a window makes conversation impossible over 100 mph.
