Anyway, while I was driving my '57 3100, the heater core let go...steam came out the defroster vents, coolant pouring out of the heater box.
I searched the shop manual online, but couldn't find anything on removing the heater core...
So how do you do it?
Thanks...

You are absolutely correct. After eyeballing it for 15 mins or so, I pulled out the battery, the firewall mounted battery box, undid all the studs and pulled out the heater core box.
Guess I lucked out on that one...

Kicking self for selling off my Taskforce trucks.
Still looking for an LCF or conventional big bolt in decent shape.
