fuel sending unit needed

Need a fuel sending unit that works, my swap for different parts worked but only reading 3/4 full it'll work but I'd like to get the full range so if you have a good sending unit out of a 1961 4 door or wagon please give me a shout.

OPGI shows one titled like this, looks like it has a return but I don't know if the pic is fully representative.

"Fuel Sending Unit, 1961-63 Skylark, Special, Tempest / 1962-63 Cutlass, F-85"

my unit has 5 screw mounting that one looks, and is in the details, as an o-ring single clip design. Might work for a 2 door since my research leads me to think 2 door and four doors used different tanks even found that the ac cars used a return line, such as mine, but not 100% sure on that.

Oh well, just did a search and it popped up by application. We have two 62 cutlass converts, built in different plants. One has a return line and one doesn’t. Jetfire has a return line, all 2 doors. All same fuel tanks. Good luck
