What year and engine size? Thanks. Kim

3420037 was used on 70 - 73 small block Abodies with AC.
Chrysler superseded that number to 3780109.

I’ll see what I got next week. Message me then if you’re still looking.

Look for a later one with the ribs on the snout, they have a larger shaft than the ones with the circles around the snout. They were originally police water pumps, but i see a lot of replacements are the one. They had a 5/8th versus the 1/2 shaft for the regular one.
