75 amp Alt, which VR should i use

I just purchased a 75Amp alternator and want to convert to an electronic voltage regulator.. Is anyone running a pre-70 style electronic VR with this setup??
Where can i get one that can handle the 75A output?

rock auto has them or most parts stores

I run a 95 amp on my 69 RR & my 69 charger looks like the stock one only thinner

Any auto parts should have it.
