I upgraded my 74 no Tach to a cluster from a 76 I think with Tach, here's what I learned

1. Used Tachs don't work, as a matter of fact all old gauges don't work, or work poorly, I would recommend a brand new one, or even a good quality aftermarket one if I was to do it again

2. I also wanted to retain my old speedo with the new Tach and guess again, can't or at least not with some doing, the non Tach Speedo is different believe it or not than the Speedo that comes with the Tach I think the front plate facia won't fit, you would need to do a swaparoo not sure it is worth it, I may be attempting it cause my newer used Speedo stopped working, see #1 above
