4 Link Bar Bushes

Does anybody have any tips and tricks to getting the rubber bushes into the end of a 4-link bar in the home workshop (Gartrac if it matters)?????
I have tried graphite powder and heating the rubber in near boiling water.
I do not have a press at home so have tried using the bench vice. Even after compressing the bush about 8mm it still doesnt even look like wanting to go in. I am worried that all I will do if push the inner metal sleeve right out of the rubber.
Help needed as I have to temporarily mount the diff in order to work out where the watts link chassis bracket goes......
