Joe, I am a computer flunky , so I can't post a link, but Ebay seller savetheclassics sells electrical connectors like that & he's in Florida. HTH.
you can get the terminals on Amazon (CLICK HERE)
you can get the plastic shells online (CLICK HERE)
if you google gm 56 series terminal, lots of sources will come up. The company that manufactures them is AUVECO, they have lots of distributors nationwide, Fastenal is one, if you have one nearby, they can source them. Here in the northeast US, Napa has them in stock or in their warehouse locally.
you can also try googling auveco part #s:
8777- male plastic shells
8775- female plastic shells
15956- male terminals
I did find them on ebay by that seller Robert, but I felt $5.99 each was a pit pricey. After going through my stuff I found some female clips with Plastic covers. And bought 1 male on Amazon. So thank you both Robert & Mark.
get a box of the terminals, male and female. I bought a bunch twenty years ago, probably two hundred in total, never at a loss now, it was a great investment in the longevity of my cars.
Bro, I have all that stuff at dirt cheap prices. Its not new, but its still good as new.
