speed warning speedometer parts

[72 K20]

Hi ! I have a speed warning speedo in a cluster that came in the last 72 that I bought. The speedo is there with the offset needle and the white needle. But that's all there is,,, the bezel has the hole where I assume there was a knob or dial to set the warning needle . From what I have read there should be a buzzer or something on the back side of the bezel.
Is there anywhere to get these parts ? Wasn't the speed warning a 69 year only option ? I don't know a lot about these ,, and don't really have any plans on restoring it unless the parts to complete it are very affordable .

Thank you in advance for any and all input ! Have a great day !!!

You are missing the adjustment cable. Also need a wiring harness and buzzer. Parts are hard to find. You can become a subscribing member and post a want to buy ad for parts or search for people selling what you need. They were an option from 67-69

Could someone post a picture of the back of one of these that is complete ? Then I could get a better idea of what all I would be looking for .
Thank you Leddzepp !! Is the wiring part of the printed circuit or an additional harness ?

Thank You
Tom

Additional separate harness that runs about $20. Clips onto the brass "lug" or "peg" on the back of the cluster

Tom:
There are pictures of a complete speed warning speedo. They may not be rare but they are uncommon, expensive when available, and are not reproduced in the aftermarket. Use a little caution, though. When any vendor says, "may need serviced" what he really means is: "I know it doesn't work but I'd be glad to lighten your wallet considerably if you're dumb enough to buy this POS".
Good Luck!

Wow !!! $295 for just the speedo !

And like VETTEDRVR said "may need serviced ".

$295 is almost 30% of what I paid for my truck . And I got the whole cluster !!

I think I'll put the one I have in a safe place and add it to my list of assets !!!

I'd be willing to trade this speedo for a fairly solid short box truck !!!!!! LOL !

I sold this a couple of years ago. It had the speed warning, tach and all the gauges with a clock I added.

Here is a factory correct buzzer with harness. The white wire clips to the brass lug on the back, the orange wire goes to a keyed power source. The buzzer mounts behind the dash.

I've seen the cable mounted in various spots on the bezel. Here is the one in my truck, I copied the location from the original bezel I had.

I have some pics of the relay in its original
Location in a truck. I have to find them
On my computer and will do when I get some time in the next day or two.
