I'm not surprised - the microfiche is decidedly odd.
 
The change is at 85-D-902500.  Up to that VIN (including yours) the calipers  
are 437 615 424A (left) and 437 615 423A (right).  After 85-E-900001 they are 
853 615 423 (left) and 853 615 424 (left).
 
Note that the last three-digit group (423/424) has swapped sides.  This is 
highly unusual, and leads me to suspect an error on the microfiche.
