Can anyone identify what speedo and tach I have here? My car isnt in front of me, I know the tach isnt rite for my 73, but what about the speedo?

Are you sure that tach is wrong? I recall you recently buying a 3 wire tach that you said was wrong for your car. If the 3 wire is incorrect, THIS tach is the 4 wire tach which is the only other one used for the 240.

As far as the Speedo, I've seen that extra electronic unit on the back of the speedo on loose speedos but have no idea what circuit it applies to. I'll be keeping an eye on this post hoping someone will offer a possible solution.

They both look the same as the meters from my 73.

The wing nut mounting requires them both to be from a 240 dash.

I bought a 4 wire, that deal fell through. I have the late 73 which takes a three wire tach, which I bought in this auction but he shipped me the wrong set of gauges. I know the tach is wrong but I think the speedo might be okay, although I don't recall that lil' box on the back of my existing speedo. Hope to get to this project (the speedo) today, If it's not going to work in my car, it will save me a drive to the other shop later, any thoughts?
