Welding in the subframe

Bump.

I am trying to slide the bar through the rear anchor afther removing the rebound stop and loosening the adjustment bolt in the front, but it's stuck like hell.
I see haynes refer to some kind of tool to use as a striking point.
Is there an actual tool for this task or do I have to improvise? And if so, does anyone have a good idea (or experience) on what I can use instead?

And again thanks for a lot of good answers :)
