I took my buzzer into the Ford dealership and they cross referenced the number with one that is in stock.
There are 312 of them available in Tennessee, where they have to purchase the part from before they can sell it to me.
There's only one catch...it's expensive! $32.88! To have them order one for me it would be $40.15!
I was able to pry some information out of the parts depo though. They told me that the part was used from 80 to 86 in various vehicles. The 80 Pinto was listed on it but nothing earlier since they do not record vehicles older than 80, and any parts for vehicles older than 80 must be cross-referenced.
I looks like my next trip to the salvage yard will be to snag a few of these buzzers from 80-86 fords.
Here is the Ford part number for those who wish to order one though.

I went out to the salvage yard today and pulled a few buzzers.
The ones used in the 74-76 Ford pickups are the same as the ones in the Pinto. They are mounted on the left inside wall under the dash, near the headlight switch.
I pulled three to make sure I got at least one that worked. Two out of the three do work!
I love how records for things so often did not occur before 1980. It's obvious that computers and the digital world have allowed for great volumes of data archiving, vs. the old analog methods of film, microfiche, and plain old paper. Sadly, for those involved in hobbies that predate the computer, much information is either lost, hidden away in unknown locations, or floating around in someones head, where they were involved in it "back in the day". Much will never be recoverable.

Well, the dealership I go to does have access to microfilm and they had to use it to identify a valve from my air cleaner. However, even then it wasn't the correct part.
I couldn't agree more, it is quite dissapointing.
I now have two different buzzers. One from a 74 Ranger F250 and two from other trucks (I don't recall what I pulled them from, F150s maybe).
The one from the Ranger is P/N 07AB-10B924-A2A. The other two match the one in my Pinto, which are P/N D6AB-10B924-A2A. After opening them up for cleaning and inspection, it appears that the 07AB from the Ranger one has a resistor or diode in the circuit. This must be the reason it has a lower tone than the others and the one in my Pinto. Either that or it is because it has a different type of plastic used for the "sound board" which the circuit bounces against to make the buzzing sound. The Ranger one (07AB) has a clear "sound board" while the Pinto one (D6AB) has a black "sound board".
I managed to get all of them working, including the original one in my Pinto, by cleaning the contacts on them with a green scotchbrite pad.
If anyone needs a buzzer, I now have three spares. I would recommend cleaning your original one's contacts really well with a scotchbrite first though. PM me if you are interested.
