Suspension bush + Crush tube issues

[Tatey]

I started putting the suspension bushes and crush tubes into my wishbones today, however I have ran into the issue of the bushes being an unbelievably tight interference fit into my bush tubes. They require a lot of force on my vice to get them to go in, however if they go in anything other than perfectly square then they deform and are pretty much ruined. I've already damaged one so far.

I've then discovered the issue of the crush tubes being a very tight fit again in the bush tubes, so tight that it is impossible to rotate the crush tubes by hand, even when they are only 1/4 of the way through.

Am i doing something wrong? I've checked the dims of the bush tubes and they seem ok. However i haven't checked the dims of the bushes or the crush tubes.

Wishbones, bushes and crush tubes were bought from SSC, so they should all be to spec.
