Howdy,

Recently acquired a 70 Charger 500 w a 440 4 barrel RB big block motor. Plenty of sorting to be done. Looking for information for correct alternator, bracket, regulator, part numbers if possible. It is currently a non-ac car so I am after a single groove alternator, square back or round back can someone clarify (Prior owner had GM alternator and funky brackets - trying to correct back to original). Am I mistaken or the 70 had an external regulator? Looking for the appropriate regulator replacement to work w the correct alternator.

Appreciate your time and comprehension. Thanks in advance.

Welcome. Nice acquisition ! If you're looking for originality, you'll need a round alternator with the external electronic regulator. Readily available at one of our sponsors, look on the sidebar.

Didn't all 1970 models use the square back alternator, or was that a mid year thing?

IIRC, 72 models introduced the squareback
Maybe we are talking about 2 different things? On the left is what I call a round back single field 1969 and older. On the right is a square back dual field that I thought started in 70. This one is my spare and dated 1971, but I believe the one on my Duster is a 1970.

Nope, that's them... I don't recall seeing that squareback until 72- later ( again, I think the 70 & 71 uses a dual-field round ).
