I now have a heater core.

Note:

ROCK AUTO DOES NOT SELL ONE THAT FITS 60-63

I ordered what I thought was the right one, and they say is the right one, but it is not. Both hoses exit up top, whereas a 60-63 needs to have one exit down low. They are aluminum.

I ended up cutting the top tube off and plugging the hole, then drilling a new hole and TIG welding the old feed tube in the correct place.

The only leak I had was where the ground arced a hold into one of the cooling tubes. Which I TIG'd closed (100hz focused the arc beautifully).

With this core, I cannot actually adjust or turn off the heat. Not likely a problem, as I can balance it with window and/or fan. Still ok, too, as an LS needs to have coolant flow between the heater hoses.

Loaded the truck for a dump run but when I went to start it, the fuel pump relay feed wire had actually lost contact, so I had to re-crimp that. Dump run tomorrow.
