<VV> Brakes grabbing

I have another set of shoes that I could put on the passenger side  
front (do they fit on the back also? no mention of this in the '65  
manual, the Basics book, or ...Keep Your Corvair Alive).  Only the  
front driver's shoe has 500 miles on it.  I'm almost 100 percent sure  
that the shoes are installed in the correct order; longer in back,  
shorter to the front on each wheel (although it is not mentioned in  
the '65 manual, the Basics book, or in Finch's book).  There isn't  
any pedal vibration, which at least indicates that the front are not  
warped (according to the Basics book).
