The next item on the To-Do list is replacing the heater core. The car has had its heater core bypassed since before the third owner bought it, which in car-guy language means it must have been leaking at some point, early on just from sitting. So stay tuned for that funfest.

Just put one in an AC car box,( out of car) and now I want to have the original rebuilt. The new one is aluminum and seems cheap to the copper unit. Curious as to what you find for parts. Im betting you will want yours rebuilt too.

I was able to source a copper/brass one from O'Reilly's. I've heard others say the aluminum is better, but I liked the copper unit.

I brought the original one from the black car to my local radiator guy. He said there is no way to successfully repair the old copper cores. They get what he called "champagne leaks" which are hundres of tiny pinholes in the decaying solder that dont show up until a certain psi is attained. He said that the new aluminum ones are fine. I got one from Rockauto for around $30.
