are my rear leaf springs still good?

Im wondering if my leaf springs are still good? they do seem a little rusty but i think they might clean up well with a wire wheel, that longer spring bracket does look a bit to rusty, I dont know if I would trust those, plus I kinda dont dig how they hang down like that, it also seems to have air shocks on there right now.

I would like the car to have that cool rear lift. also those tires are just during the restoration! I wanna get some nice beefy ones when complete!
