71 Scamp Dangerous To Drive
Do you have the alignment numbers? Just because someone is old school doesn't mean you got a good alignment.
Best performing tire depends on what you're doing with it, but your current tires are not likely to be causing your current problem. You should be able to track straight down the road and handle decently with BFG T/A's if they're in good condition. If you want a corner carver they're gonna fall short, but again, I really doubt the tires are your current issue.
I can't see the other side of the rockers so I'm just going by what the pinch weld looks like. But the rear rail where the outrigger and shackle mount are needs to be replaced. Same for the whole section where the front spring mount is. Obviously I only have the pictures you posted, there's a whole lot of frame rail in between those two points. If the damage it limited to just the areas shown in the pictures, you could probably section out the rear frame rail out at the back. The area where the front spring mount is could be problematic, again, it's hard to tell how much rust is there but that giant hole is not good. You could remove the front spring mount, cut back to solid metal (if there is any) and patch that section and then reattach the spring mount. And that could be done without pulling the whole car apart, although you'd have to drop the fuel tank, rear axle, remove the rear seat and pull the carpet back at the least.
With rust there's always more than what you see, and honestly having sectioned and patched and having replaced entire frame rails it's often easier to replace the whole rail if extensive patching is needed, since the whole rail is spot welded in and large patches will take a bunch of welding. But replacing the whole rail takes a lot more tear down.
I'll get a better picture of the shackle area, because yours has been replaced by what looks to be a chunk of square tube. But the front spring mount should look like this...
