I am ready to start on my 70 challenger. It needs rear wheel tubs inner and outer, trunk floor, and both quarters and both rear frame rails. Where should I start. Where do i need to brace it before I cut thing out. I have welding experience and feel somewhat confident, this is my first time. What is the best plan to tackle this. What should be done first to last. how do I align everything. I would love to hear from the experts and see what they suggest so lets hear it. Is this too much for a first time experience. I want to learn and need to start somewhere. I know to get AMD metal thats the plan.
