Excellent pictures!
Considering I just turned the throwout bearing washer around last weekend at a mere 17 hours of labor....I'm going to tackle this project later. Take some pictures when you are done, if you can measure the thickness of the forward tab before you start, and then again after it fits correctly, we'll be able to figure out how much to remove....would be very helpful for me.
Thanks!

I've read something about using a small Nissan Sentra alternator, but I can't find any info on it. For the race car, need half the amperage of a stock car. Anyone have any idea what the deal is?

Ok, finally completed this project. I kept having to trim the bolt holes and the ears get it to fit. Just reassembled all the cooling and air tubing that bad to be removed to get to the alternator. Refilled the radiator, connected the battery, and cranked it. It started and ran, but zero volts on the dash gauge.
Getting bit of belt squeal when I revved it, so adjusted the AC tensioner, but now I have the battery on a trickle charge before I try again in the morning. I will test the voltage at the battery as well.
For those that have done this mod - how did you wire it up? Did your stock volt meter work?
Thanks

Thanks guys. That is how I wired it up, so something may have come loose.
I have ordered the factory connector, so that is on the way. When you say run a wire from the battery to the alternator, you mean from the positive terminal to middle tab (the on that currently has the jumper running to the big bolt where the main wire goes?

Update. I am not an idiot. It was wired up correctly, my issue was the belt was loose. I adjusted the tension to eliminate the squeal and I am now seeing 13.5 to 13.8 volts at idle.
I will get it off the jack stands and bleed the cooling system, and take it for a ride for the first time in a month.
Caveat - the idiot part is still TBD. After all, I did purchase a 951....

Well, after 3 years and 20k miles, my Quest alternator finally died this morning. We had a short service and a nice eulogy before removing the alternator and placing it in its final resting place; the trash. But for $135/shipped, can't be the replacement price!

Only 20k? That's a pretty short life for an alternator. I'd hope/expect to see at least 100k.

A chevy sprint-pontiac firefly alternator is what a guy in Calgary supposedly used on a track car.
