I am a new 1980 BJ40 B-engine (10/79 production) owner and am adding a heater/AC aftermarket kit to it for my girls. I plan on getting the one from Nostalgic AC with the Sanden 709 since it requires less HP (thoughts on if there is a better one), but my BJ came from the factory without a heater and the Nostalgic kit hooks to the existing heating supply and return lines. I am trying to figure out where in the engine compartment these hoses connect. Here is a screenshot from SOR's website. Guidance please.
