Pretty basic for this. I drilled the spot welds out and removed the panel to straighten it and modify it to conform with the outer panel. In the books the plan is to put this part in first and then fit the outer panel but I needed to make the B pillar virtually from scratch and modify the quarter panel to fit the door which was my only reference for this part of the car so the process was to fit the B pillar to the door that was mounted to the A pillar and checked for squareness to the sill. The the B pillar was fitted to the latch worked correctly and then rear quarter positioned so it aligned with the door. This didn't go so well so the outer panel had to be modified. The inner panel needed some less drastic surgery and I built the closure for the strip that is used to hold the inner trim in place.
