What it looked like before

This is one of the pics of my 79 before i re-done the body all sheet metal done by me myself and i.

 

I can't tell from the photo, but is the rear eaten through or is it ground down to metal?

 

Rear was eaten through floors were swiss cheese mainly the quarters and the floor.

 

One of the reasons i save it from a crushing death is the frame is perfect motor and trans from underneath looked all new (motor mounts,trans mount,and the tranny were flawless)
