don't want to waste anyones time. looking deeper its a no name tach in the factory spot. can still use bezel but can use any tach. no need for sending unit. thanks.

It may be a Sun Super Tach 2 under a OEM bezel. That's what I used when I changed to CD ignition. Put some black tape over the call outs.....

If you got a Factory Tach for under $50,000 dollars it's probably aftermarket!
