Well amps, stereo and EL Fans you will need a 100 at least. Get a 130. EL fans can be 30 amps each. Likely not fond a 3 wire Alt 130 amp.

I actually have a 1 wire, don't know amps, on the C10. PO did a fairly hack wire set up for it so I was going to go back to 3 wire using a spare one I have. I will just pull the original VR and get a Tuff Stuff one

IMHO the external works a little better at idle but less of a problem if you have done the headlight relay mod.

If HEI or Pertronix Dizzy definitely use a solid-state VR. IIRC Autozone brand also has a solid state one (likely offshore) but I have the Tuff Stuff one (made in USA) on my 67 Camaro. IIRC it was $13 on Amazon when I got it
