I've got a '62 and am trying to replace the broken heater levers with new steel ones. Other than taking out the 2 screws in the top of the face of the panel and unscrew the support arm that attached so the bottom of the assembly, what do I need to do????? Feels like something is still attached at the top of the opening but I can't find any screws and there's not enough room to see anything.
Perhaps the following link will help out: http://www.stovebolt.com/techtips/interior/heater_control/index.html
Wish I had that link before starting. Thanks for the help. Would've taken all of the guess-work out of it. The problem ended up being a boogered up hole. Looks like someone tried to force it out at some point, which caused the screw to dig into the hole it went into on the dash. In turn that caused the heaters controls to catch on that boogered up spot when I tried to take them out. A quick shot with the dremel and it came out without any problems.
