I screwed up!! Advice please?

I had an a arm tab rusted loose on mine after I bought it. Probably not a big deal. Mine is a driver so I welded some steel in to reinforce it and it has been fine for 2 years. It’s under the car, so nobody will see it. A meatball job is ok if it is solid. Find somebody to weld it up, maybe a local muffler shop if they will do it.

I agree with Steve, looks like a good deal to me if that is your only real issue.
