If there are lines painted on the lens where the tach is then it's not a tach dash. It would have the numbers printed and an obvious hole that you could see through and the printed circuit wouldn't be flush on the back...it's "stepped" out for the tach to fit on the back. Sounds like you have the deluxe factory gauges with 7 hole vs. the three hole gauges with "idiot" lights for the center for oil and temp...but not a tach dash.

The option 1 is the one for converting a non-tach dash using your gauges. (470-75 discount I offered = 395)

If it were a tach dash without a tach and the printed circuit was good and I could re-use the tins that would save 125 off the price. (270)
