Level sender as I remember it was different pre 90-1(?) , nothing after market comes close. I think they flipped the ohms for full and empty around 91.
Had a hell of a time finding a nos 86 20 gallon sending unit for a carbureted jeep.
Gas tank was easy to source, never knew how beat up the old one was until I pulled it.
I'd recommend New for the tank just because, you'll also get a extra gallon or two of capacity because if the way they make it.
