Clock to tach conversion

[Ron Roberts]

I would like to convert my clock to a tachometer. I know it has been done and it would be good to have some help. I think it is worthy of another tech article if anyone is up to it. I have a 73 Ghia with the stock speedometer next to the clock. It would be great to have the tach look like it was meant to be there, with the same Bezel, needle and center cap as the speedo.

Thanks
Ron
