On my '71 Scamp, the original connector is a 90 degree rubber connector that completely covers the terminal, nut and all. (My sending unit has a nut securing the threaded terminal). If you're not concerned about being correct, I'd try a female bullet connector for size. I just went down to the garage and checked, a yellow bullet connector is a fairly close fit. Not sure what guage that is as I'm a novice electrical guy. If you're concerned about the nut and terminal being exposed to the elements, you could use some heat shrink to cover the exposed area. Leave a little extra and let it "unshrunk" on the open end of the female connector. I hope I explained that right. Otherwise, I guess you could check around and find a donor and splice it in. I'd think it shouldn't be too hard to find, being a common item to most Mopars. Again, I'm no wiring guru, and hopefully I'm not speaking out my butt, lol. Good luck.
Edit: Or you could follow the advice above and just buy a new one, LOL. Guess he got the jump on me.
