I am replacing the heater core in my 1977 corvette with a/c and I can not remove the cover to the heater core after I removed what appears to be all the screws holding it.
I looked out side on the firewall and did not see any screws or bolts that may be holding the cover.

I would greatly appreciate it if you someone could tell me
how to remove the cover.

Thank You.

Somewhere in that list of steps is the reference to the bolt sticking through the firewall which I think you are missing. Easy to spot once you know its there.

If I recall correctly, there is 1 hidden nut behind the evaporator box. I think you need to remove the portion of the box closest to the engine. G/L

Did my 72 a few weeks ago.....3 NUTS inside - under what "used to be the passenger dash" and ONE nut outside.....accessible from topside with the hood up. I removed nothing under the hood except ONE nut.
Take it slow...not an easy job !

I did mine a few months ago. Three bolts on the inside, and one nut on the outside (engine-side passenger firewall).

The hoses are kind of a pain to disconnect too...I ended up removing the floor heat shield thingy to get to the hoses.

Good luck...
