I don't currently have A/C but may plan on installing it (351c 2v w/ original intake). Need some clarification on the original heater hose connections. What were the original ports where the A/C heater hoses connected. I'm guessing right front intake port and top port on water pump (labeled as #1 in pic below). If I'm incorrect let me know. My question is what are the ports labeled as #2 and especially #3 used for and what type of fittings should be in #3. Currently hose was recirculating from #1 to #3. If you can't tell that's a picture of my water pump.
