I would like to convert my old gauges to electronic. I no longer have a tach drive distributor or a cable drive transmission. I do have a tach drive electronic signal ans a hall effect VSS speedo signal (Tremec TKO).
I see some information where people have gutted aftermarket gauges and done this. However, aftermarket speedo gauges that have odometers or gauges that have a 270 degree sweep (Corvette has a 300 degree) seem pretty rare. I looked at making some with the stepper motors that have been used in cars for 20+ years but can't find anything where someone has successfully made a driver for them. Same with the tach. However, thats the easiest way to get the 270 degree sweep (very complicated for air core driver).
I realize I will have to make new gauge faces but that's OK. I have also looked at late 80's Firebird gauges but driving them appears to be as much a challenge as the stepper motor.
