FD Alternator Swap
This may be a dumb question but what all is involved in putting an FD alternator in a 1st gen? (Carb'd) Stright bolt in, pulley swap etc

Some rewiring will be involved.
an S4 alternator is a straight swap. Here's an image describing the wiring changes you'd need to make to use an S5 or FD alt.

Yeah. I have a stock reman alternator in mine and it runs all my accesories fine. Including my electric fan, and my sound system. I've got a amp that's puling a lot of power and it's powering a 15" inch sub. Stock alternator should do, but, and S4 alternator swap is extremely simple. Where as S5 is a different story.

Got the FD alt with dual sheave pulley to work on my REPU. It's great. Be sure to wire the exciter wire up to a constant on +12 volt source otherwise it'll slowly, quietly drain the battery when you shut the truck....er car off.
Don't get the steel dodge caravan pulley some guys sell. It's larger diameter than FD so it'll underdrive the alt. Low voltage at idle especially. Get the aluminum dual sheave one I think japan2la sells. Mazdatrix has them too.
