Putting polybushes onto the wishbones

[brainbug007]

I started trying to get my polybushes and made a dogs dinner of the 1st one. I can't get the poly bit to sit flush with the bone as I made the mistake of trying to put both bushes and the crush tube on at the same time... Now it's too wide to fit in the suspension bracket and I cant figure a way to get it back out to put it right. So my question is whether to try getting it out somehow or can I just widen the mouth of the bracket slightly to allow it to fit in?
