The replacement pcbs don't have cylinder selection, it's not needed.  Simply calibrate with the correct frequency for the amount of cylinders.  In your case as above for 8 cylinders.

 

Factory tachos from that era are not perfectly accurate, but were close enough for flogging around the streets.

 

That's why the manufacturers refer to them as RPM indicators. 

 

I guess a philosophical view would be that if you're going down the road revving at 6000rpm, your eyes should be on the road, not the gauges, or learn to shift by ear.
