does anyone know if the heater core from a 4 runner WITHOUT a rear heater will fit into a 4runner WITH a rear heater?

im aware its bigger, im assuming to allow for more heat, so that everyone is comfy, etc.

i took the rear heater out of mine, and i need a heater core and the tubes (which are impossible to get are leaking.)

the heater core for the 4runner without a rear heater comes with tubes attatched to the heater core, the other does not.

 

iirc, the heater core with rear heat is shorter than the heater core without rear heat.

Hit up the plumbing department for some hight temp water heater sealer. Comes in a small tube. Works great on those friggin tubes.
