So, My moms car has the big clock. We've decided it needs the tachometer. So I read this thread:

Tachometer retrofit - shortcut option?

And that sounds like the best way. I assume from reading that, the 84/85 with the pick up in the adapter plate has the tach amp built into the gauge. So all you've have to do is wire the tach pickup to the gauge. This sounds like the simpleast solution electonicly speaking. I've never had a problem with the tach in my 84, so this makes me think this is a sound solution.

BUT

Is this the simplest solution? My mom has a new tach amp she bought for her first car. So if I do set up the early style tach I have a tach amp. The engine still has the bracket on the front. And I don't have to drop the transmission and pull the flywheel to install it. So this seems like the easiest option.

Has anyone retrofitted the early style tach?
