Heater instrument panel differences for 67?
Here's a picture of the general idea I'm going for. Right now the vents are just in there loose, but they should snap in to the appropriately sized panel. I popped them out of surrounds they came with and just have them kind of hanging loose in the hole right now. It looks like the would fit about perfect inside the chrome edge loop of the radio surround. I may have to tweak the hole in the dash a little, but it's pretty close now side to side at least. Maybe a little tall up and down, but I can always 3D print a filler panel or something if I need to. The stock bezel should cover it pretty well though.
