Cheapest place for torsion bar removal tool/clamp?

NEVER EVER use vise grips or other tools that gouge up the springs!!!

You can wedge a scrap of 2x4 up in the suspension and use a pry bar to push the TB to the rear after removing the LCA lower pivot nut. Works great.

No comment on the 2x4, but agree 100% on not using vice grips. Not very wise.
Find or build the correct tool.
