To add to earlier answers, you can use any alternator that you can disassemble, remove the fan-pulley drive side and install the LM (65-69) Corvair fan-pulley and drive side (because only the Corvair fan will cool the alternator), but then you need to make the electrical changes based on the alternator you've just cobbled together. Corvair clubmembers, and Corvair club publications tell how to bypass the stock alternator if you are using an internally regulated alternator.
I would guess that most conversions used '70s era GM alternators that had the same four bolt connections hold the working part of the alternator to the drive side mount, fan and pulley (which varied from engine to engine in GM's lineup).

As for rotation, the fan is different ( I think).

Guys,
The rotation direction may not matter - but the fan direction does. If swapping to an internally regulated alternator - make sure you use the Corvair fan.

No corvair alternator came from the factory with an internal regulator.
Rotation direction doesn't matter.

There have been several different caliper brackets offered. Since you already have 15" wheels, you don't need to look for one that uses really small calipers, I'm pretty sure you can do this with mostly common GM parts. I recall both Stinger Motorsports (David Clemens) and LeVair (Michael Leveque) have offered a set of brackets and a parts list.
The big thing is getting the f/r balance correct, you may well need a new master cylinder too.
Caveat: I've not installed one myself (yet). All the above is what I recall seeing around the Internet. Good luck!

The self adjusting system, when properly set up works when backing up.
No need to slam the brakes, if there is enough clearance, the shoes move
the lever arm which clicks the adjuster wheel.
This presumes that the system is working exactly as it should. Often that
adjuster at the bottom is not in great condition.I
It needs to be clean and very lightly lubed so it can easily turn. I use
"dry lubricant" after I get the assembly off the car and cleaned up
thoroughly.
Also have to pay attention to the stamped marking and get the adjuster on
the correct sided. One is Left and one is Right.

Norm,
First, no Corvair came with internal regulation but you can convert to
that technology.
Second, as far as electrical power, it doesn't matter which direction the
alternator spins. However, the centrifugal fan on the alternator's drive
shaft requires the proper turning direction. Your alternator may overheat
with the wrong fan. The Corvair alternator fan is different from all other
GM fans. You must reuse the fan from your old alternator on the shaft of
the new one. If you get a generic alternator, you will probably need to
switch housing parts for mounting purposes.
If you are mechanically inclined, this is pretty straightforward. There
are descriptions of the process of switching to an internal regulated unit
in a couple of the Corvair publications.
If there is a possibility of adding lights or other power drains in the
future, get an alternator with higher amps. Why do the job twice?
Good luck,
Doc

Was the Corvair ever originally equipped with an internally regulated
alternator, or did they all have an external regulator?? If using a non-Corvair
alternator, is rotation direction a factor?
