The bearing carrier is essentially a cam. Its that way for your chain adjustment.
Do you have it turned too far forward or backward? if so that would put that front bolt hole on the bracket too low to get the bolt in.

Well it should raise and lower the bolt holes as you roll the carrier forward and backward. That is the reason for the bushing with the 2 mill flats that is on your swingarm and the carrier goes over when properly mounted. The carrier slides forward and back, but also up and down. Try taking off the 88-89 brake stay and rolling the carrier 180 degrees, then remount the brake stay. See if that works.

Its all an eccentric, so it all moves. Axle, carrier...everything. However, I must be wrong since you say so.
