I've got to remove the deck hinge torsion rods on a 69 b-body, and thought it'd be worthwhile to ask first, just how much force is stored up on them.

I've got the deck lid off, so do I just pry the spring out and hope for the best, or is there a certain way to do it that makes it easier?

I did some googling and didn't find much at all, so I figure it's not exactly rocket surgery but still, better to ask and not get whacked by the thing in the process.

Thanks for any advice.
