.. it's been found that some of the slop can come from where the bearings insert into the plastic mold itself.. if this is the case, you can try scoring a crosshatch pattern into the plastic with a hobby knife which will tighten it up for a bit.. we've gone as far as creating a small flat spot on the bearing case and fitting grub screws into the molds.. (similar to the hinge pin mod, pics on the previous pages). We have located someone who's looking into the bushing idea again.. We will post should that produce positive results.. hope it helps..
