Yeah that leaf looks toasted! Pretzelized. Your brake backing plate looks a little sketchy?? Hope that isn't brake fluid stains on it.

That 400 bucks seems like a high price... I had four multilayer leaf springs made for me from scratch by Betts Springs, (big spring company), and it didn't cost THAT much. I then made the u bolts myself out of high carbon 1060 rod. Bent them with heat. Threaded them with an impact wrench and lots of cutting oil.

Don't know what tools you have or if you don't mind spending bucks or would rather spend time...
