Bolt in frame connectors

Tim, I welded the Mancini bolt in connectors (same as mp) in my 69 Dart conv today. You will have to trim the outside rear more than you want to get them to fit with the torque boxes. So I just drilled a bunch of 1/2 inch holes in what was left for plug welds. I had to move the parking brake cable up in the cross member. You will be instantly happy at the difference in the car.
