replacing heater core in 77 Corvette w/air

[stevolwevol]

I believe I have a heater core that's leaking. My windshield is fogging, I smell antifreeze, etc. How difficult is to replace one of these?

It's mainly time consuming. You'll need to remove the "box" under the dash which will require accessing mounting screws on the engine side of the firewall.

Way easier than one on a Fox body Mustang.
