You're welcome Scott! Yeah, that sounds like a good plan to hold off on buying the transmitter until you receive the cluster to see exactly what tach you're dealing with.

Even though the clusters are different for 60-63 vs. 64-66, the section where the tach is located stayed pretty much the same. So there is a possibility that the original 60-62 tach has been swapped out for a 63-66 tach that doesn't need the transmitter.

If the tach in question ends up being a 63-66 version with the built-in electronics and happens to be for an 8cyl, an alternative option to an adapter would be to send the tach to a repair shop and have it re-calibrated for your 6.
