Oh, how I feel your pain. [smiley=wall.gif] As did I, you have the US Civil War "Mini Ball" centerstand. Argh...
The ground contact points do not appear to be worn too flat but there may be sone stand-to-chassis wear that gives the unit an over-center look.
Yes, the stand design changed late '82 on. Beside having better geometry, the stand has a proper foot pad that doesn't destroy the sole of your boot.
Found the replacement for my '81 'hernia inducer' for cheap on eBay. Simple swap out and so much easier.
