OK Hood, you have the Poly type.......
I would tighten them up some more than you have so they are firm with the bush and washers but not disfigured to the point that they are squashed. If you leave them too loose you will allow too much movement and they will rip them selves apart from too much free play and will become distorted and cause even worse wear.
They are an energy part, so they are made to have a little bit of tightness. Make sure you apply plenty of Graphite grease on the bushings aswell, they are prone to squeek if not lubed enough. There should have been grease supplied with the kit.
