I had this problem on my old 201. I removed the spring and took a wire brush on my grinder to the area to determine the extent of the damage. The area around the upper spring mount was fine, with only a little rust. The factory attachment is not the best on these and failure is common from what I could determine. I ground back to bare metal all around, re-aligned the perch with a hammer, then re-welded with my MIG, making the whole attachment a solid seam. I then added reinforcements on either side, primed with epoxy primer, seam-sealed and undercoated. The repair was doing fine 2 years later last I saw it. Total cost about $10 as I already had the tools. It took me about 3 hours to do, and much of that time was spent getting the spring in and out as I had never done that before on that car.
