Alternator

[DLMc]

My 74 being a low mileage car has the original alternator on it. I installed some Edelbrock heads on it and was able to modify the brackets so it would fit. It works fine but wanted to upgrade to a one wire. The problem I am running into is the new alternators housings are deeper in depth by over 1/8". I looked at the remans and they are also wider. These won't fit my application with the Edelbrock heads like the original one does.

Why not just use the original alternator?

Because it's over 50 years old and just wanted to have one on hand.

Okay,

Is it a square back? Like this:

The old adage applies: why fix it if it's not broken........like vintage wine.....age enhances...especially original alternators.....

We have a board member that rebuilds them and has cores. You could swap in a factory type one with ease for peace of mind and save this one as a known good spare. There are kits to up the amps if you need more juice than stock.

I have run into this problem with a swap meet alternator, the back does not clear by the bearing.

The secret, when attending swap meets, IS TO KNOW THE PART NUMBERS (or physical dimensions) of the components that you are seeking. DO NOT RELY ON THE VENDOR.....he say it'll fit (to make the sale), but offers no guarantee.....the old adage applies: The Latin phrase for "let the buyer beware" is caveat emptor......case in point.....alternator case configurations....old round back style vs new square back style. Just my opinion........

I agree but I plan to do the power tour and wanted one on hand if this one was to give out.

It won't be the alternator that fails...it will be something in the ignition system....ECU, MSD, COIL OR BALLAST RESISTOR......

cudaize is the one that does the rebuilds. He is sending me a date coded one right now. I was happy with the pics he sent of mine. He’s been selling on here for awhile.

I rebuild my own alternators and starters, using NOS MOPAR PARTS, which I've sourced at swap meets, etc. Easy to upgrade alternator capacity but changing the stator coils plus diodes and still look like origional unit....no big deal....or mystery.......

Part number and vendor with a clue? Your way above my price range in alternators. Looks like a Chrysler alternator, square or round, how many field wires. Sold.
Buy them very cheap, test them, good or parts piles.
