Yes and no.The 1974 used a cable driven tach.I assume by "new style" you mean electronic.To do that there are 3 possible ways.First,find a 3/4"-16 hole if there is one[doubt it] and screw in the proximity[tach] sensor.Second,get a signal generator and drive it from the mechanical cable drive[those are old school C.O.E. tach drives,and need an instrument calibrated to it,unless you have a programmable tach.Third,use a programmable tach and run it from the "R" terminal on a Delco alternator.Figure pulley drive ratio to get RPM of alternator,multiply by number of poles in alternator gives you pulses per minute,calibrate tach to it.Just use a cable driven one.Al
