rear beam removing hubs

[Matt]

Engine is being done now, I mean I want the car back together in the same week ideally. Don't mind working on both at the same time.

I've never touched rear beam drums atall, so what I'm gunna do is take the beams, smash the abs trailing arm off, preferably with Tb attached. Then smash the trailing arms off the non-abs beam,
Then refit the abs trailing arms on the non-abs tube.

That's right yeah?
Is there anything going to be damaged on the trailing arms? My current beam is completly collapsed. So what would I need to look at?
