As I recall, that is a uni-body vehicle, with no real full frame to support it. Keep in mind that what you are planning on doing is dangerous, even for a qualified and experienced technician. I have seen that done numerous times, with disasterous results. They have been done in shops with very good reputations. All welds have to be perfect. Any failed weld or improper joint will increase the likelyhood of failure. The vehicle can break and cause serious injuries or even death, for any reason.
You also might want to check on the insurability of a vehicle with that kind of repair.
THIS HAS GOT TO BE ONE OF, IF NOT THE MOST DANGEROUS TYPE OF REPAIR THAT CAN BE ATTEMPTED.
