Tach mount for my Belvedere

Hello, I have a 1966 plymouth Belvedere and mounting a Sun tach but dont want to drill thru pad or mount to column,are there any options out there for a mount that would work...thanks

I have a 66 belvedere and i mounted my tach on the A-piller. I have pics on the main index under projects and survivor it's not the best pic but it can help a little

I fabricated a U shaped bracket and screwed it up through the instrument cluster above the heater controls. Then I ran the harness through the top
slot in the heater contol. This put the tach on top of the dash without drilling through the pad.
This is on a 66 Coronet by the way.
