Setting aside the question, what design moron would think of doing it this way? I can think of a few ways to avoid pulling the hub, etc. which seems totally unnecessary for such a trivial purpose.
1. a dab with a wire welder on the now-rounded oval hole and maybe a cleanup with a dremel will fix it. For the price of having the dealer do the work, you can buy the wire welder, take a few classes, and have money left over, and have the joy of fixing them for your friends.
2. I bet I could figure out how to make a two-piece backplate from yours and one more with a good hole. I bet you can, too.
3. I once needed a washer with an oval hole. I heated a washer, held it loosely with vice grips (so it wouldn't buckle) and squeezed it in a vice. Voila! not-round hole, just the thing to put behind your buggered hole and catch the knobs on the spring holder.
4. You wouldn't have to be very creative with nuts and bolts to replace the funky nail-looking shaft with something threaded that screws in to a flat nut and maybe a washer to spread the load, behind the backing plate. It looks like there's plenty of room back there if you're creative with ways to hold the nut to get it started. Hint; a magnetic retrieval tool should work fine.
5. Expanding, threaded rivet. there are such things; they look like pop rivets but have a threaded center. Clean up the hole, pop in the expanding rivet, use a screw to hold the spring against the brake shoe. Or for that matter, an ordinary pop rivet and a tap to thread the center hole after it's popped in place, run a screw into that. There need not be a lot of stress on the screw, it just needs to be snug enough that the brake shoe doesn't rattle and flop around.
6. You don't actually need a complete circular piece to catch the knobs, you can get away with a fork-shaped piece that slides past the knobs from behind. I'm thinking something made of thin steel with a slot the exact width of the shaft, a slight bend in both ends so it stays in place and can be gripped to install, slide it down behind the little sticky-out knobs. Done. If you can't find the threaded rivets, this would be by far the simplest. I believe I've seen such a piece used for something else hardware, but can't think right now exactly where.
) and everything was going fine on wheels 1,2 and 3 but when I took off the rear nearside this happened:
