Where to buy correct alternator for a 1969 340 swinger non a/c car

I need some advice on where to buy the correct alternator for my non a/c 340 swinger. The original alternator is long gone. I have a stock wiring harness and a new old stock 69 voltage regulator. It seems like most of the aftermarket and rebuilt alternators available are much higher amp rating than my stock one should be.

I like the way Rockauto's website works. Look it up by your application and all they have available wil be listed on the same page. I don't know the amp ratings for your car but it's probably a 46a. or there abouts. @Mattax can you help here?

I thought the square backs are better at low rpm. Are they a direct replacement? (bracket wise)

Here is the place that I use to get mine rebuilt... They make their own windings in house and are local to me in Bridgeview, IL...

They can rebuild them for your choice of amperage, you just specify which one that you want... They once told me that the higher amp alternaters do not put out as much at idle as the lower amp ones but ramp up with RPM.

For a 69 non-AC car you want the single filed roundback alternator with a single groove pulley on it for the belt grooves to line up properly when you use the correct factory alternator brackets.

I may have a spare alternator laying around that can be used for a core...
