my powerflex upper wishbone bushes fitted perfectly.. I did not use the washers on the advice of powerflex.. they said that the supplied washers were a packaging error.. and anyway.. purely from an engineering standpoint they are totally unneccesary..
I have got a feeling that there is, or has been a quality control issue at powerflex or the manufacturing tolerences on the subframe were quite wide.. after all they were not designed for tight fitting polybushes..
in some cases it may be necessary to fettle the bushes to fit.. the centre metal spacer needs to be a tight 'interferance fit'.. I guess if it really will not go in then the only option is to skim it.. I would not force it.. could damage the subframe..
If in doubt give powerflex a ring.. they are very helpful
