I finally found a complete instrument cluster in a 81 turbo in the parts yard. Usually these clusters are completely dissassembeled and strewen all over the car when I find them in the parts yard. Someone does this to pull out the valuable speedo gear, but it is also disappointing as the remaining parts quickly become unusable.

Anyway, I've wanted to put the large tach in my 82 wagon and now I have one. And I found the small clock and bezel over a year ago. Recently my tripometer reset stopped working, so I also want to fix that while I'm messing with the cluster. I also have an 83 240 turbo with a broken odometer that I intend to fix with the left over parts from this job. My question is, which is easier:

Changing the odometer reading (adding a few 10 thousand miles- max 80k) of the cluster I just purchased since the other parts seem to be working. A assume since it's the turbo cluster, and mine is for the NA model, I might need to remove the extra mechanical counter device too.

Or -
swap the parts to make the cluster I want.


Seems like just figuring out how to change the odometer reading might be easier than taking both apart, but I'm ready for the brick board to guide me a little further in this effort.

I'm considering I might as well do any other mods to the cluster while I'm at it like disable temp compensation.

--correction, the cluster I purchased appears to be from an 81 Turbo, not 84 as I originally posted. It does not match the cluster shown in the Bentley 240 manual.
