To the  all-knowing list-

I have some slop in my distributor, and purchased  another to rebuild.  It 
had a little wear, so I ordered 1 bushing,  expecting to replace the lower.  I 
got it apart and discovered there is  no lower bushing in the housing.  Is 
there a bushing in the block  also?

The stock Corvair distributor has only a top bushing. The lower part of the  
distributor drops into an aluminum guide just above the oil pump. That 
functions  as a lower bushing for the purposes of the Corvair. There have been 
rebuilder  who have "double-bushed" the distributors during rebuild. To me that 
means you  have to align three "bushings" when installing the distributor - or the 
 distributor will "align" one of them by itself. At least one premium 
rebuilder  has installed a sealed ball bearing at the top of the distributor, using 
the  original lower "bushing" as the other aligning point. That adds a barrier 
to the  oil that has a tendency to migrate up into the points area, when 
crankcase  pressure occurs.  - Seth Emerson
