Frame Rail Connectors
Not sure how the original torque boxes are installed, when I installed the frame connectors in my Duster I did the connectors first and then added the torque boxes, welding them over the top of the connectors.
If the TB's are just spot welded in, I'd be inclined to drill out the spot welds on the inside and pull them out of the way to install the connectors, then weld them back into the connectors afterward. But I haven't seen a set of stock TB's, so that may not help. Even if they're seam welded I think I'd probably go the same route, although it would be more time consuming. The other solution would be to cut a slot/notch in the TB at the frame and slide the end of the connector up through it, but that would make welding that side of the frame connector a bit more difficult.
Here's mine for reference. Mine are home built 1.5"x3" steel, but the connection at the end is pretty much the same as the Mopar pieces, I think mine cover more surface area but its the same idea.
