That same hardware bag is cross referenced for the 550 and the 600
You are correct, I own 600 as well. I don't think I will lose it again but I am very that I know for sure where to get one.

Or get a machinist to make one for you. I think parts bag would be cheaper.

Clearly the spacer stops you from pushing the OWB up against the top radial bearing with the possibility of locking it up. It is odd there isn't a similar one to stop the bottom bearing from doing the same.

Maybe on careful assembly you can just leave a small gap between all three bearings.

The spacer was introduced when Align started using the helical cut gears.

The helical puts a slight upward axial load on the main gear/Sprague clutch. The spacer ensures the clutch is pressing against the outer race of the radial support bearings, as axial loads on the inner ring would damage the bearing.

There is no need to put a spacer on the other side, as the loading imparted on the bearings isn't in that direction.
