Torsion Bar clips won't install

Is the engine installed? If not, you could loosen the K frame bolts and try to knock the right side forward just a tad. I don't know what will happen when you tighten the bolts back up, might just shear the clip off.
Did you paint the torsion bars? Any chance you might have some paint build up on the end that is inserted into the LCA, or perhaps some dirt in the LCA before you assembled?
