intrument cluster questions

[Guest Anonymous]

will the early model instrument cluster (one without wood trim '73 or so) work on a later model '76. Also, how hard is it to install the tach onto an automatic car. thanks for the help!!

physically, clusters mount the same, but note that later cars may have different rear end ratios. Speedos are calibrated for the rear end with which they will be used. Therefore, if you use an earlier cluster, it likely has a speedo calibrated for the 3.64 rear end.

I believe, and I could be wrong because I haven't personally verified this, that a tach could be swapped for the clock. You would need to have a single wire sensor from the coil or dizzy to the back of the tach for the tach sensor. Don't know if that is present in a car that came with a slush box, but it would be easy to run the wire.

hmm, on my e30 i was able to swap differentials without having to worry about the speedo. im guessing that 02's calculate mph differently?

I've done this in my wife's '76 and in my '75. You'll find the black wire with the connector in place when you remove the cluster. It connects directly below the tach in the middle on that side of the cluster. You will be left with the clock setting knob in the middle of the tach face unless you want to swap that out also.

the 2002 speedo takes off fromt eh tranny so any changes form there back (including tire size) will affect the reading.
