Drivers side is welded the same and is close to the frame but not touching as the passenger side is.
I am guessing the springs are used as the gentleman I bought the car from had a full parts car to swap the drivetrain over, said it was a 72 dart parts car but came with 727 trans and 8 3/4 diff where this yellow car was originally /6 auto and a 7 1/4 diff I’d guess with small bolt pattern, all of which is long gone now
