Installing custom rally dash this week
I had Red Line Gauges switch the small tach to a gas and volt gauge, and then put the tach with shift light in the large hole. The shift light can be mounted any where not sure where yet, and the sift light controller is a dial that is tucked under the dash. I sent them the gauge cluster and they changed it there, I don't think you can just by the tach, but you can give them a call.
