Default Won't Start

I have a '79 C3 Auto L48 with a complete Top-End Rebuild. She ran fine 3 weeks ago, I go out to start her up for a quick cruise and nothing. When I turn the key to start, no clicks, no crank but interior lights go dim. I have proper voltage at battery terminals and same voltage at generator. Starting to think it the Starter but haven't had much time to continue to troubleshoot it. Any direction would be appreciated. Thanks!

Check and clean your ground, especially the short one to the frame behind the drivers seat to the battery

This is the usual suspect. The grounds seem to be more critical in a c3, probably because the the body is made of fiberglass.

12.5 volts at battery terminal and the same at the alternator but when I put the key in the start position the lights are dim and I have a voltage of 9 volts at battery and alternator. There is no clicking noise and the starter never cranks. All grounds and connections are good. When I attempt to start the engine all interior lights go off. Ideas?
