Coolant Temp and fuel gauge pigtails

short and sweet, I’m looking for those pigtail connectors that attach to a 72 Duster fuel tank and a 383 mopar temp sender. It’s been a pain in the butt to find these. Every similar pigtail (GM) is too small. Could I just put an eyelet on the wire and sandwich it between two nuts on the pole??

Help me Obi Wan Kenobi, you’re my only hope...
