Thanks I am already running the 5/8 plug. Im running the autolite equivalent to the rc12yc can't remember the number off the top of my head. I had planned on buying a starter but I found one in storage I can't remember what it came off of now. It was either my 86 318 or the 77 360 I don't know tbh lol. But I bench tested it and it worked. And begin around Christmas and I was extremely tight on money I said what the hey let use it lol. That will be something I will go back and replace eventually.
