Front suspension looks like Chevrolet Corvair. Rear looks like modified mid '60s GM intermediate, like Chevelle, Tempest, Cutlass parts. I don't recognize the front brake components, but might be GM since looks like the rest of the stuff is. Before spending too much time and money trying to rebuild that bunch of stuff you might be ahead of the game driving it awhile to see if you really like the way it works. My guess is it's not going to be very satisfying and you might do better by getting a replacement chassis assembly that isn't as cobbled. Those parts were a popular (sort of) way to get independent suspension under an old Ford in the late '70s. They didn't work that well and were quickly supplanted by better, more readily available parts.
