Jim :
 Does it look like both sets are Bosch?  I don't know if the wear on the
set that was in the used 73 dist I got was from that dist because that dist
does not have much up/down play . I have not taken it apart to know if the
upper shims in the trigger cam are worn.

 The set Tram sent me has a bit of rust on the face and back side on the
one side , it's on the metal part where the point contacts are . I got most
of it off using a toothpick. I just don't want rust getting in the lube on
the cam. I don't know a better way to do this. Should the pivots be lubed ?
