What Products are Needed in the A-body world?

As mentioned, I would need to start with chassis components/fabrication type work. I know there's a demand for sheetmetal(Ive been stuck looking forever as well), but the time and money involved in presses, and tooling dies is WAY above my level just yet. I do appreciate all the input thought guys! I think I will start with front suspension components, a good fitting roll cage kits, frame connectors(possibly with driveline loop mounts), etc.
It was mentioned that a new transmission crossmember may be desireable...as the stock sheetmetal unit is not the strongest. What's everyone's opinion on this? Thanks!
