wire spade connection on onan starter solenoid

GOOGLE
"Delco Packard female spade connector". I posted a picture here of one not long ago. I believe larger NAPA stores carry them. They are unique and difficult to manufacture. They also do not come loose unless you want them too. I've crimped over one million small terminals in my lomg life and what I write here comes from the School of Hard Knocks. Engines vibrate and the rules get harsher.
