Its by the rear control arm, when i purchased the car the guy said it came with the Torque Box reinforcement plates... Are the torque boxes cracking or is this another problem?
That's a torque box, I dont know what your previous owner said about the reinforcement plates. Either they werent installed right or its not on there at all.
I would have the "Battle Box" style reinforcements welded in on that car if you dont have any and weld that crack of course. I got an upper and lower set of powdercoated box reinforcements for $60 on eBay.
Is the installation of the torque boxes difficult at all? Let me know if there is anything special that i need to know. Thanks a ton for everyones help!
