Heater switch assembly problem
 
For some reason the heater switch assemblies in BOTH my 67 GMC and my 68 C10 have developed the same problem. The front faceplate has separated from the rear switch pivotal bracket. I did not realize until today when I rebuilt the 67 one with new switches that the separated pieces were held in place with permanent rivets, and mine no longer have the flares ends to keep them together. Has anyone else had this problem, and if so how was it fixed? Very strong glue perhaps? I could not find a thread on it.

Not sure I follow you 100%, but I'm going to give it a shot anyway. If you are talking about the faceplate coming loose from the frame that is pretty common. There are a few threads on repairing them. Here is one.

If you type "Repair heater control" into the google search box above, click on the circle in front of 67-72chevytrucks.com, then click on the google button you will find some more threads on it.

They break pretty easy. Mine was broke when I got my truck and I broke the one I was replacing it with.
What I did was to drill through the rivets and clean through the face plate. Then I installed stainless steel screws with nuts on the backside.
You can see the screw heads on the front but by being stainless steel they blend in really well.

I used some heat to unstick the cover. Now drill and countersink the bolts then glue the plate back on.

Thanks for the replies and the thread link gentlemen. I followed the thread link instructions and drilled out the damaged rivets, then reattached the assembly with stainless screws and lock nuts. This thing is now SOLID and permanently fixed! Now that I have practiced this with my 67 GMC, the 68 C10 is next. It does not look bad either.
