Some cans, like the dyna3835 1500, have a step machined on the inside so that the stator is pushed in to the step to set it's position. Others like the AQ are just one inside diameter, and you have to measure where it goes before you glue it.
So it depends on how your can is made. You could heat the can and push the stator in deeper if yours doesn't have that step. That would leave more room at the rear to machine off.
At $26 you don't have a lot to lose.
