For the necessary tolerances with the plastic housing of the several compatible extruders and their versions you may design to use this kit, please allow some axial motion along the main shaft.
0.25mm on each side is enough.
This motion doesn’t affect the performance of the IDGA and actually it allows the IDGA to self-center with the filament.
