1970 442 alternator question
I am cloning a 1970 Cutlass to 442 specs. The original alternator is externally regulated with a voltage regulator mounted to the firewall. The manual says 1970 442's used an internally regulated alternator. I want to go with the internally regulated one. My question is, do I need the firewall mounted regulator, or do I need a different one? Is my cutlass wiring harnesses compatible or need modified? Any info would be very helpful.

FYI, real 1970 442s used a unique alternator with an open face and a distinctive rear housing. Correct ones are hard to find and priced accordingly when you do.

Thanks Joe. I have an alternator (new or rebuilt) where as the back of it looks like the one pictured, but the front is not openfaced. So You are saying, omit the cutlass firewall regulator and make the harness mods?

Yes Joe, the alt I have looks very close to the one You just pictured, except mine has 5 round holes on the back where Yours shows 8 slots. Also, I had to remove a rubber square to expose the field wire tabs on the top.
