lowering torsion bar

[connorp]

so torsion bars, is there a threaded hole in the end of it? if so what is the thread size in the end of it? and what is the outside diameter of the splines? how long are the splines as well, like how far will the bar have to be pulled before it comes out?
I'm thinking about making a puller to lower my torsion bars instead of whacking them out with a massive hammer.
