[Spridgets] differential mea culpa

[mdrowe]

I confess, I resisted Ron's suggestion that bad radius arms were causing 
clunking.  But this morning as we headed out shopping, I said to my 
wife, "This is what Ron says I should check.?  When I touched it, it 
moved!  So I wiggled it, and it was not the bushing that was bad, the 
arm had fallen completely off the bushing and it was rattling around on 
the bolt with no bushing at all.  I haven't a clue how there was enough 
room in there for that to happen.

So much for my judgment.  Ordered new arms.
