I'm talking to a guy about buying a mechanical tach- including tach drive- off a 478 diesel

I guess the most important one will it work on my 305? Is it "out of the box", "plug and play" off the camshaft? I know the camshaft is prepped for it.

Second, this tach an interesting dial. Colors may have faded with time, but there is a tan arc from 15-2500 RPM with "shift" over it (yellow? orange?) a green from 25-3400 with "drive" over it. The last I can guess- 34-4000="danger" Anyone care to explain this dial to me?

Can the hour meter be reset?

I know it's not the tach that normally be used with a 305, but it's pretty interesting in the dash.

Looking at my owner's manual after I bought my truck yesterday, I noticed in the accessories section the tach that was picture appeared to be a ribbon tach- kind of surprise to me, at least for a truck.

Thanks!
