Waterpump on driver side. If you still have air pump look under bracket and between top alt.





Right under that nut/stud that hold Alt. bracket And behind crank pully

you may have water pump from newer model
i have 85 and have electronic tachometer, with signal wire from ignition coil.

The 73-79 Spider parts book says that up to 1977, the tachs were mechanical; 77 and up are electronic. However, an electronic tach doesn't show up in the wiring diagrams until 1979.

Does the face of the tach say 'Electronic' on it somewhere?
