GM Alternator Mod Question

I'm down for the Winter, but need a new Alt. The only thing that's keeping me from trying the GM Alt. Mod is the fabrication of brackets.
Surely, somewhere, out there is something that can be used to make this fit with maybe an extra washer or two. I've been changing Alts for years. They all have a long bolt at the bottom and a Short one at the Top.

OK! Before I start trying to re-align the Drive belt, which GM Alternator are you guys using? A 2013 Cadillac or a 1965 Buick Regal? GM covers a broad spectrum. If you start with Dimension Specs, surely you can find another Alternator that is very close to those specs. So what if it's a Ford. They're all outsourced and use Import Plugs.

I used a CS 130 but almost anything can fit. Typically you have to cut the mount's foot down since the spread of GM alt's foot pivot is narrower then what Fiat used, after that it's pretty easy.
Can't the master thread back at the moment, probably in N54

I think updating this page will be my next project.

Thanks

I can deal with cutting things down. I just can't weld, so I can't build stuff.

I picked up a cheap Alt for my Geo. Turns out it came off a Canadian Car and the "Hot" post grounded against the block.

I don't expect anything I do from now on to be "simple". The one thing I hadn't considered when I bought "The Red Bull" was electrical problems. I understand it just enough to know that I don't know Shyt.

That's why all the Brown Wire Mods seem strange to me. I can see taking the Excess Voltage away from the Ignition Switch might be a good idea, but in the end, you're still running all these systems, with extra relays and multiple circuits where anything can go wrong off the same 12 Volt battery.

My Toyota (and Suzuki) Alternators put out about 14 Volts * 2000 rpm. Why shouldn't I adapt one of them to my "X" project?

One of the benefits of the GM conversion is more amps, easier replacement and cheaper. It's been a few years but i think you cut about 1" off the mounting foot pivot (wait to you have an Alt in hand to measure, then fab up a top bracket (from a $15 Mr. Gasket generic) and you're done. This thread has a link back to a good one.

here's the write up

When I tried the above I snapped off the water pump bolt that was supposed to be used to mount the top brackets, then I had to get creative with a top mount (ended up with a heim joint type thing from a Abram's tank a member sent me!). Don't break that bolt.

I just lived this....

As it turns out for me, making the bracket was actually very simple. Wiring it took me a little longer to figure out (I am electrically challenged).

Tony has a great guide for the bracket - Item #3:

There is a question in my thread asking about a single wire alternator. I don't know enough about it to weigh in. I am using this:

I think Jeff was alluding to...

Note that it only involves a hacksaw and a drill!

BTW... I was told back in 1984 by a part-counter guy that there was such a conversion... but I couldn't see the forest for the trees... and the mount was all wrong.

Accessing it from the rear trunk made it really EASY and I didn't know I had such a "door" for 15 years! If you have a '78 or older, you'll need to carve one out for yourself and you will NEVER regret it! GO back to Best Of in the 1.0 section to find the details...

Good luck with your conversion.
