Do you have inboard springs? I like the way the Hotchkis connectors are, but make my own.

Here's my take. For cars with stock spring hangers the loads are being transmitted at that location. That is why Chrysler made torque boxes, to connect the thrust to the frame rails. By using the Hotchkis style, you are strengthening the unibody in the right areas and eliminating the need for torque boxes. For cars with inboard springs (in the framerails) putting the connectors in line with the rear frame rails does the same thing. I believe that on most cars the spring hangers line up with the front frame rais as well.

If you fastened pieces of 2 x 4 lumber in there it would still be an improvement. I've seen guys use single round tubes, double smaller round tubes, 1 x 2 cold rolled rec. tubing , 2 x 2 square and 2 x 3 rec. as well as the laser cut stuff. When you get up to 2 x 2 square, 2 x 3 rec. or the laser cut pieces you'd have a hard time telling the difference unless it were a full-time drag or autocross car - in which cas you'd probably have a bit more tubing inside helping to keep things from twisting.
I was curious about the engineering aspect. I figured that at some point the larger sized connectors would be an issue of diminishing returns. The reduced ground clearance and ugly non stock appearance wouldn't be worth the minor additional gain.

I did go ahead and weld in the 3x3 frame connectors and torque boxes. The car handled great before but afterward, the ride felt more solid. The car soaked up dips and bumps with fewer rattles. It was quieter. I fully endorse this upgrade to anyone except those with OEM correct restorations.
Pics if ya got any. i'm looking to do this when it warms up on my RR
