Hello,

Not all 544/122 insturmet cluster internal components are interchangeable!!

I recently had to do a custom restoration on an insturment cluster for a 1967 122 project I am doing for a customer.

Before the car went to paint, I removed the insturment cluster and removed the chrome bezel for polishing and I disassembled the lense assembly, because the customer wanted the metal face plate that usually has the gray crinkle paint to match the body color of the car.

When I did this I noticed that some idiot in the past had put in dash illumination bulbs that were too long and the green plastic bubbles that color the dash illumination were melted and it would be a total pain to swap these with another cluster because the retaining ring is staked in and these rings provide the ground for the bulb so it has to been done right.

So I dug out what appeared to be the same cluster with the later larger diamater threaded shaft for the speedometer cable hookup and good green illumination lenses with the intent of just swapping in the customers odometer and trip meter, but the little rod that drives the odometer/tripmeter just under the speed indicator drum would not fit nor interchange.

Upon closer examination, I saw that one cluster used a plastic gear on one end and the other used a bronze gear with different numbers of teeth.

So I had to reset the odometer to match the customers orignal odometer reading.
