Clutch Update and Alternator Upgrade

[austex]

Hey everybody, first off, I just wanted to thank everybody who has helped me out with good advice. I'm a new Z owner and own a fixer-upper, so I've needed a bit of help lately! It turned out that what was wrong with my clutch was...the retainer clip on the clutch fork (that clips to the pivot ball) was bent ever-so slightly and wasn't doing its job. I'm fine with getting a new clutch since the one I pulled off looked ancient. Kinda figured it'd end up being something small...

Anyway, I'm having various electrical problems which are very similar to the ones described over at The Z Garage (http://datsunzgarage.com/engine/ -- scroll down to 'Alternator Upgrade') I own a '74 260 and figure I might could benefit from the same thing that he did, by putting in an alternator from an 81-83 Z. (I know he's talking about a 240, but still...) Figure I could also benefit from properly grounding everything too.

Any thoughts? The previous owner apparently had a massive sound system, and basically had everything electrical that wasn't necessary to start the car disconnected.

What do you make of the circled area in the picture below? I'll take some better shots tomorrow if need be.
