I'd like to go with the Toyota alternator (after reading the Mad "3 wire vs 1 wire" tech info) but wasn't sure where in the heck I'd find the connector to do it right. The Internet is a beautiful thing! Found this company that sells a "repair" or conversion pigtail for the Toyota alternator Thats it isn't it? Scroll down to page 4....... http://www.nwreg.com/pdf/catalog/nwr_catalog_c.pdf

Maybe OT but is there something in the tech archives to do the single wire/new alternator conversion? BTW, what are the pros and cons of a single wire vs a 3 wire vs OEM alternators?
Scott, AndyF turned me on to this link.....

Great info! Basically the one wire is a dumb system and just pumps out 14.5V to charge a battery. In a race car with a very simple, HD, BIG WIRE system this would be OK. But in a car, especially our old cars with bad connections and relatively small wires, the 3 wire alternator has a sense wire. This should be connected to a main 12vdc junction like the stud on the starter relay where it can then compensates for voltage drops. The 3 pin connector also has an idiot light output. In the article above it says this is a good feature to wire up since a voltage gauge will show low voltage (discharge) but the idiot light will give you a heads up to a situation like a thrown belt.
Good read - check it out.
I just picked up an inexpensive Toyota alternator on the Bay and AndyF's bracket setup from Greg in FL. The guy on Ebay ALSO sells the 3P round plug with pigtail for $10. Can't wait to get that voltage regulator OFF the firewall. Then I may move the MSD box somewhere else like inside the car. I like that simple look. As it is with the battery in the trunk and manual steering. The motor looks TINY sitting in the engine well. Might go to an electric fuel pump also. I LIKE that STARK, BARREN look. This small Denso alternator will help with that "look". Plus it make the engine easier to work on

The correct Toyota alternator already has the v-groove pulley on it. So I hope that is the correct case style to work with the bracket kit. If the Denso or Toyota part number matches up to what the instructions call for then you're okay.
I don't know. The picture on the Egag site the case looks different than the one on Andy's site.

Nope it's not different. Look closly at the boss by the lower mounting hole. Same as on Andy's website. I REALLY looked them over. There IS anothet case style that is VERY similar but slightly different on that lower mount hole and boss - longer and more of a "12 o'clock - 6 o'clock" positioning instaed of the "12 o'clock - 7 o'clock" as selected by Andy.
I'm gonna test fit it tonight. i'll let you know. Them alternators are like $150++ anywhere else.
Found a link to a 90A upgrade "kit" for these also.

Install went great. NOPE I didn't WIRE it yet - gotta dig thru the service manual to figger it out. Not sure if I should cut the voltage regulator and extra alternator wires off or not. To do it right I would need to retape the harness and don't feel like doing it right now - think I may cut them off and tape over them for now.
Not sure what to do with the extra regulator holes on the firewall. Probably just LEAVE them. Would be cool if there were some small push in black caps to just barely cover the holes - gotta be something like that at the hardware store or ONLINE.
Gotta get the AndyF recommended 45" belt tomorrow. The stocker 48"er is a bit long.
Also gotta redo all my fuel lines. Redid the carb fuel lines over the weekend with auto parts store stuff. It's coated with some light green covering. Looks like crap. Then my six pack fuel line from the pump up to the filter needed to be tweaked for the new bracket plus it needs to be longer. May just have Inline Tube bend it. They'll bend up anything that you mock up with a piece of coat hanger. I'll probably order a pressure regulator and upgrade to 3/8 lines. Still wanna stay with an OEM kinda look. Holley has a plain Jane looking aluminum regulator. Have to see if it comes in a 3/8" unit. May need to up the mech pump to a 3/8" Carter.

I have thought about doing this conversion also. Not a real electrical genius, so I'm kind of hesitant. One ? I do have is with the increased current from the new alternator, are there any upgrades needed to the factory wiring system? I'm just wondering whether my crusty engine wiring harness will hold up.
Shouldn't be a problem if you make the amp gauge bypass per this article http://www.madelectrical.com/electricaltech/amp-gauges.shtml
