Well, After sending the original radio out for rebuild and removing the center console and most of the ducting, I replaced the repaired radio ( just needed cleaning and lubrication / adjustment for AM and FM stereo operation), I took the car out for a little test drive. Very COLD here at 65 degrees( kidding) but with clears skies. Anyway, I noticed a gurgling coming from the heater core area. Sounds just like water running through pipes.
Did your heater core " make noises" before it started leaking? I will say that I don't relish replacing the core after reading the process you went through here and it is not leaking.
Also, according to my PHS, my car did not come originally with an 8-track player even though there was one installed when I bought it. Is there any interest for what appears to be an original 8-track player and all brackets and wiring?

Two of the studs are behind the passenger side cylinder head and the third is under the heater blower motor which requires the lower mounting points of the fender to be unbolted, in addition to the entire inner fender. You then put a small block of wood to hold the fender far enough out so that you can properly slit your wrists on the sharp metal while quarter turning the ratchet to remove the single nut from the stud...and the remove the lower heater core hose from the core outlet. It then promptly wedges itself into the kick panel tranny hump and lower portion of the dash.
This is something like solving one of those twisted nail puzzles where there is only one way to get the two metal pieces to unhook from each other. I found the secret: You have to first push the housing toward the driver's side (the radio removal was critical to this move), then you have to rotate the housing so the heater core outlets face the floor while pulling the housing diagonally toward the passenger door. It takes around 10 steps of pulling one inch, rotating one inch...lather, rinse, repeat, until the whole assembly can come out of the car.
