Not what I said. You can't drive the torsion bar through the LCA, that's not possible. The hole in the LCA is smaller than the torsion bar on the other side of the torsion bar lever.
If the bar will slide out the back of the rear anchor, you can remove the nut on the pivot, slide the bar back, and the LCA will drop down some so you can strike the back of the LCA and drive it off the end of the torsion bar. Driving the LCA off the torsion bar will be more effective than trying to "pull" the bar out of the LCA, which is basically what you're trying to do now.
Those bars are more than dirty. And regardless, they're a 43+ year old critical suspension part that supports your entire car, with an unknown history and who knows how many miles. And even if they were in great shape, these cars were undersprung from the factory, resulting in that extremely dated, "drives like a barge" '70's handling. What you do is up to you, but of all the things that can be replaced for $200 or so the torsion bars are one of the first things I would replace, and the last thing I would try and save money on.
