1980 Mustang Fuel Sender

so i am building my 1980 mustang coupe and it was a 4 banger..im dropping a a 5.0 carbed set up in it...;and when removing the fuel lines the feed nipple broke off the sending unit....my question is what can i replace it with? i cant find a replacement sending unit. Can i use one from a later year up to 85? Or where can i order it.. LMR only has them from 82. Not sure if they are different, And to replace the tank is fine but they dont come with the sender..lol..and the 87 plus tanks are bigger and wont fit properly, thanks
