sure, you don't need the 130a output those offer, but its no harm to have it - and i like knowing that if i have a problem, it has to be in exactly one place.
that said, i've done the 3g upgrade 4 different times if i remember right, maybe it was 5. they're usually like 30 bucks at the junkyard, including as much of the wire harness as you choose to leave attached to it

I also have been told by Gary that the high output alt may cause a big problem with my 52 ammeter so I dont want to go down that road at this point

Since your ammeter just senses the current instead of having it run directly through it there shouldn't be a problem if your alternator puts out a bit more than the original generator - like 65 instead of the original 40 amps. In fact, it isn't going to hurt your truck nor its wiring if your alternator puts out 130 amps. In fact, I'm not sure it would truly hurt the ammeter, but it would sure peg it.

I've only caught bits and pieces of this thread, but has your alternator got an internal voltage regulator? If so, you should not need an external one. Also if you check, even late 60's fords used 6 volt guages in a 12 volt system; and used a voltage reducer. I used a "runtz" voltage reducer in my truck from Speedway Motors. If this is off topic, my apologies. I'll shut up now...
