Heater Core Replacement (non-A/C)

[In The Ten Ring]

Congrats on getting yours back together so easily. I still have mine out and all I have left to do is clean up the control lever at the bottom of the box and paint the outside. *OH, and I need to remove the old rubber (circular) gasket and replace it, I have the new one.

I would LOVE to remove the surface rust from the metal flap inside but as it's held by a rivet, I am unsure if I can ever replace that or get it to work again, so I will just leave that surface rust there.

I removed some leaves and pine needles, not as much as some I have seen on here.

My local radiator shop found a brass heater core for me as they could not fix the old one.
