Your torque boxes are ripping. I just welded my cracks up because I had the exact same problem. There are torque box reenforcements available for under $100. I just used some scrap angle iron and my MIG to weld it up. I found my crack when installing subframes. See pic for the torque box strengthening I did.

Subframes connectors have nothing to do with the torque boxes. The tear is from the axle twist usually on the passenger side. The boxes are just sheet metal. You may find some re-enforcemets at 50resto.com or even on crapbay (ebay).
Stick your head under the car where the lower control arm goes. If the box is cracked or tearing, you need re-enforcing NOW.
The welding is generally necessary. If you lived close, I would weld them up for you for nothing!
Subframes not fully installed in the pic. These subframes cost about $6.00 in materials. Shipping alone would cost more. I dropped the car off of the jack stands today and Planted a NICE two wheel smoke out. No clunks, no slip, just power.
