UCA Bushings don't fit?

I won't be able to get to the car until Friday, so no measurements until then. One of the old bushings was really bad and it spun freely inside of the control arm. The guy said he filled up the spot that was causing it to spin with weld and then he sanded and/or ground it down to make it circular. I never saw how bad it really or how he actually installed the bushing. I'm thinking that the other side might just need to be hit with a mallet because I can almost fit it.

That is surely suspect to an issue. Good Arms are easily found to replace them, I had to get one as the UBJ was welded at some point and ripped it apart with a long leverage bar before noticing the weld. No issue with the bushing area but! I suggest making a simple measure across either side to see the difference. Tight is good IMO. You may be able to salvage it but is it worth that? I replaced my welded BJ arm prior to new bushings very cheaply!
