Good news....

I found a perfect 107 instrument cluster with 160 MPH speedo. The gauge face bears part number 107 542 28 01.

Bad news...

It came from an unknown donor.

There are no tags on the back to indicate what rear axle ratio it was originally used with....

I have attached a few photos of the cluster, including the back of the speedo itself.

On the back of the unit, the numbers '095/002 / 21' are stamped into the metal housing, followed by the charcaters 'W1155' and the numbers '9.76.'

The number '34' has been hand-written over the '21' (mentioned above) and the number '12' has been hand-written over the '9.76' described above as well. This would indicate to me the unit has been calibrated at some point, but to what specification????

below this group is a blue triangle ink stamp, with squared edges, that reads '112 1.77' and a similar looking green triangle that reads '30 12.75' respectively.

My intention is to install this into my W116 with a 2.47:1 rear axle with 205/70R14 tires and have it read correctly. I am in hopes that someone can either interpret these markings, or point me in the direction of someone who can.

Thanks very much for your help!!!!
