SOLD Rebuilt Alternator 3438171 Single Pulley

[cudaize]

Rebuilt 3438171 Alternator dated 15 70. Has 2444478 single pulley. This part number is listed for 6-cylinder cars but is basically the same as the ones used on small and big block cars without AC.

What is the difference between the 6 cylinders and big blocks?

 

[Jerry Hall]

Physically nothing. In all likelihood it's a 45 amp unit, which most were without AC.
