Don , If I remember correctly , that's what I was using on my car when I flat towed. I think that picture was from 1969 , before the lettering and bumpers and the "GRUMPY BOX" I never took off the tow bar tabs as evident in this pic. I put 2 slots in the front bumper center bar to accommodate the tow tabs. If any body here has a '57 and wants to "Flat Tow " I still have that center bar.Does anybody besides me remember those old "Towing hubs"that they used to make?
