My car had it's diff replaced and I wanted them to rebalance the wheels because there was a shake in the steering wheel at 60. They replaced the diff, but told me that my rear right wheel was bent... and told me the price to replace it was $760

I did cut a corner too quickly when some asshat was tailgating me and I was turning off and didn't feel like getting rearended. I was only going probably 10 and I cut it too sharply. I better replace it before I put I sell it, hate to pass something like that off onto someone. Do you guys know where I could buy a single wheel at a non-ridiculous price?
