While it's off the car take the subframe over to the frame straightener...chains, anchors and hydraulics do better than a BFH. Otherwise the car will sit funny and the sheet metal alignment will be harder than the usual '69 effort. Measure the diagonals and heights (on jackstands) per the frame charts...
This is '67-'68 but on jackstands the ride height doesn't matter, just the mirror images.
