Looks like that one is a 78 - 79 unit, which should be a direct bolt in.

For your tach signal, unfortunately, its a bit more complicated. The alternator will not produce nearly the right signal, but, you can install a newer type of vaccum pump which will have a signal generator on it. You then need to run the signal from the vac pump through a signal ratio modify, then to the tach from there.

I'll PM you the email address of a guy who just recently installed a tach into his turbo 6.2, so he can help you with specific parts you'll need to get.
