You're going to want to have a picture handy for this to make the most sense.
The bushings are fine, but the inner metal sleeve inside of the bushing is too short. The bushing and sleeve should be the exact same length.
Try to find a picture of the metal washer/plate (?) that sits against the whole outer bushing surface. That plate is should touch the metal sleeve and the bushing.
Instead, since the inner metal sleeve is recessed, the plate only presses on the bushing, which you don't want.
Solutions:
1. grind down the bushing to meet the sleeve
2. build up the sleeve to meet the bushing (by adding washers)
3. get an entirely new sleeve of correct length.
Since this is a budget UCA option, getting new sleeves might defeat the purpose of saving money. I went with solution 1 because I couldn't find correct washers, but many people do either. Doesn't really matter.
