E body exhaust Hanger question

Dont most all dual exhaust ebody have the rear exhaust bracket that goes through the trunk? The extra hanger in the picture was bolted on the frame rail when I got the car. Anyone seen this type of hanger before maybe A body?

Thanks

That extra hanger does not belong there ,remove it and leave only the ones bolted to the trunk floor.btw the floor still has to be drilled for the bracket that goes inside the trunk

According to the assembly manual, these appear to be for a B Body. Stick em in the swap meet pile..
