Re: Adapting original tachs with alternator setups

I would try the modified tach approach first.
You could always mount a generator and alternator.  Later model tachs, and
aftermarket tachs are cheap and plentiful.
If you are ready to go through the trouble of modding a smog pump maybe you
could look at just modding the alternator with some sort of slot in the
shaft and a bolt on boss that adapts the tach drive cable to the alternator.
Just a few thoughts, not meant to discourage.
Cheers,
