I have been looking at the Cobalt gauges by AutoMeter and I must say, I like them best.

I think down the road I plan on converting all the gauges in my car to autometer cobalts with the Covans classic bezel at summit. Only one problem
. The Cobalt speedo is electric and my car's speedo is mechanical.

The stock speedometer in my car was an 85 MPH, swapped for a 145 MPH by the previous owner and It's already having trouble giving false readings. The Cobalt is a 160MPH.

What parts/mods would be needed in order to make an electric speedo work in a mechanical speedo car and work right with the higher MPH reading?

Is it as simple as grabbing a mechanical to electronic speedometer box at Hawks or is that the jiffy rig way of doing it?

 

I'll be interested in how you do this because when my interior goes back in in was planing on using all Autometer Cobolt gauges.
