You've now free'd up the action, but getting it to actually work is a whole different matter entirely. You likely won't be able to get the bolt to close all the way at this point, the hammer and firing pin will be stuck, so will the feed mechanism. Now you have to take the rifle apart.
The soaking should have helped to loosen up the screws, so what you'll have to do now is disassemble the rifle. Look up a disassembly guide for that gun. Then, make sure you have the right tools. Make sure your screwdriver bits fit EXACTLY in the grooves on the screws. You'll have to deliver a lot of torque most likely and a bit that just fit just right will just not work. It'll slip, fuck up the head, etc. You may have to clean the screw heads out a bit with a dental pick, teeny file, wire brush, etc to open up the groove.
Now get them screws out, you'll probably have to crank on them. They may come out, they may not. I suggest a short screwdriver with a decent size handle so you can get close and reef on it. Alternatively, a mag-bit driver in a 1/4 socket on a small ratchet might work better.
At any rate, if you get it apart you'll have to carefully and thoroughly clean each part. Emory cloth, sanepaper, wire brushes. Be careful when taking out the small parts, they'll be seized in too. A small deadblow hammer made of nylon or brass will help a lot here. Get each part clean as you can, then blast everything off with brake cleaner to make sure all the dust / filings / rust etc is gone.
