Just curious.....

I think I found a 2.47:1 differential, but need a speedo calibrated for the axle. Are these tough to find???? Car will do over 115mph flat out with the 3.07:1 axle, but I want less cruising rpm @ 70mph.

I'll bet you can find a SEL 450 or so and pull it.
rare but possible...

I have 2 W116 instrument clusters. One from a 73 450SE and one from a 1980 450SEL.

No idea if either is the one you are looking for.

Apparently,

There is a cable count 'code' on the back of the cluster that gives some indication as to what axle ratio the unit is calibrated for...Robert

If you really get desperate, I know there are mechanical signal to electrical converters for the speedometer. You could take the original mechanical signal, run it through the electrical converter and put a speedometer from an 81-85 SD in there (which is electric). Of course you would need to calibrate the unit read the correct speeds. I believe they cost around $100. Probably not the cheapest or simplest route, but an option if you can't find a 2.47 mechanical speedometer. I believe Carleton knows about the signal converters.

The R107 and W116 used interchangeable speedometers for some years. The 380SL, 380SLC and 560SL all had 2.47 rear ends. A speedometer from one of those models should swap in.

Won't work. Those are for 126s, the car in question is a 116.
