It's like this, the more work you do to them, the stronger they'll be. You'll gain some durability just from seam welding the stock torque boxes. You'll gain even more durability from bolting in a set of torque box reinforcements. Lastly, you'll gain the most durability from welding in the torque box reinforcement.
I guess what I'm saying is that every little bit helps, but if you want to get serious about reinforcing your torque boxes, seam weld them, bolt in the reinforcement kit, and weld them in. Problem solved.
I'm a bit late to this party, but I can say a few things from experience with my '93 LX. I put in a Torque Arm and Panhard bar about 2 months back. WHen those went in the UCA's and Quad Shocks came out. Soon after I started hearing pops and creaks that got worse and worse. Not knowing about this Torque Box issue I had the Spring Isolaters replaced (they were shot anyway) and greased up my new UPR Chromally Adjustable LCA's. All this didn't change anything.
I then found out about this torque box issue but didn't find any torn metal in the torque box area. I ordered up Wild Rides Battle Boxes and installed those. Unfortunately nothing changed. Just bolted in didn't help a bit
I just got the battle box and torque boxes welded today and it helped a lot, but it didn't fix things. I still have some creaking and popping going on in the back. I looked things over today and I cleaned and painted the welded areas. I think there are some areas/seams I going to get welded and I hope this shuts this problem up for good. I know my torque boxes are tons stronger than they were, but the noises from back there still make me a little uneasy when driving "spirited".
Below is a link to some pics of my install, hope you find them useful.
