Tony,
You worried me for a second and made me think about it. I even went down to the garage to confirm what I was thinking.
If you look at the bars the out portion is larger in diameter then the inner portion. The new spring plates from Elephant racing are open on the outer end with "C" clips holding the bars in. So remove the "C" clip and pull the bar out from the big-end...
Hope I explained that well???
Elephant racing torsion bars for the quick change spring plates (which I just bought) are threaded at the end so you can insert a bolt and easily pull the Torsion bars for either ride height adjustment or replacement. I was hoping I could just drill and tap mine for easy removal.
