I have not determined by reading the posts above if you have an '80 model or not nor do I know the difference between an '80 model or mine (which is an '81 model) but my F-100 did come with a dealer installed A/C which has the separate controls in the "dash pocket" like your truck does.

When it came time for me to upgrade to a woodgrain style dash (I like the look) I purchased a nice one off of ebay (along with a woodgrain radio bezel and "no cruise" steering wheel pad) and it all went right into place where my original black dash bezel was. I had no trouble at all with the swap.

The "pocket" in the bezel is the same for all trucks and it is left in intact with the dealer A/C switches installed. The plate mounts to the front of the pocket and it has the two switches mounted to it. All very simple and interchangeable.

The two A/C vents in the bezel hook to the air ducting hoses (which come off of the A/C box from the passenger side) easily. I like to use a long tie strap on each hose to keep them from coming loose.

Behind the passenger panel (that contains the other two A/C vents) is the big plastic A/C box where all of the cold air circulates around and then on through the four vents.

When I restored my pick-up I yanked the entire dash and did a color change and then reinstalled it all back. Here are some pics of what my F-100 dash looks like now.

 

My next project is to re-pin a tach dash into my truck.

BTW - I still have the black "camera case" dash bezel if you want it.

 

Mines a 82 F150, I got a new instrument cluster in, going to test it out first to make sure all the gauges work otherwise I am using just the tach out of this one and installing it in my old housing. Then I planned on doing the LED conversion that I seen on here that was a impressive look brightness and color wise. Then I will have to either fork over the $100 for a new indicator for the cluster since this one has an over drive indicator, or just remove the one from my old unit and reuse that.

I found out that the dash vents are black with no trim, so what I thought about doing was simply getting some chrome paint and brushing it on the edge of the vents it will give it a dull aged chrome look similar to the passengerside.

Only thing is mine doesnt have a pocket anymore, the pocket was either completly removed or was never there. The panel I have doesnt say ford anywheres on it like yours. So I might have to do some investigating before I buy a new bezel to see if I can make it work.

 

Not quite sure what the original poster is looking for without a pic, but I have the dash panel with AC vents, in Black and Gunmetal gray - no cracks. Also have the matching piece for around the HVAC/radio. Top two screw holes on the smaller piece are cracked partially off, but a small washer under the screw would hold it in just fine and be out of sight.

BTW - mine looks exactly like the one in the pic posted on page 1 of this thread, the E-spay pic?

NW Ohio - make me a decent offer + shipping?

 

I was more looking for information. I picked up a clock off ebay for $28 that works and is in like new condition, this requires the swapping of the bezels and mine is dealer air and I wasnt sure mainly because of the pocket. Mine hasnt been apart in years but I do remember taking the switches out and pulling them out the back side as there was no pocket left.

I was also curious if there was any differences between the dealer and factory vents. I thought about popping my dealer vents out of the dealer bezel trim pieces and use reproduction factory vents but I found out from a previous poster on here that the factory vents are larger than the dealer ones.
