Should work OK. The fuel outlet on a 58 was in the middle of the tank, while the outlet for the 1960 may have been on the driver side. Physical dimensions were the same however.
My post 60k car came with a nice earlier tank.The oulets are different as mentioned,you need driver side outlet,This wasnt a deal breaker for me,I would have drilled a new hole in the floor.However the tank would not fit,The most obvious if I remember correctly was the fuel inlet could not be lined up with hole in body.I got a new tank from Jorge on ebay,fit perfect,and then found that my filler cap assembly didn't work and I needed the matching push on filler cap.The inlet hole sizes are different.
