Father-Son 1974 Duster Project
I managed to pull/push the dent out of the driver side rocker.
I drove 3 tech screws to half their depth in the dent. 1 in the crease and 1 on either side. I then tack welded the screws in place. Then used the curved end of my carpenters flatbar and a block of wood to pull the dent out. After seeing daylight through one of the threshold screw holes to the one of the new screw holes I made in the bottom, I decided to drill a 1/2" hole above the dent. I then used a 3/8 steel pin to tap the rest of the dent back into shape.
