Fuel tank straps on 74 dart 360 sport

Hi everyone I have a 74 dodge dart sport 360 bought a new fuel tank and it matches the original but it wants to be close to the frame rail on the passenger side and like 4to 5 inches away from the rail on the driver's side it stays like a 1/2 in. From the shock on passenger side and it is like 3 in. from the driver side any advice or should I use a bfh lol
