Has the .45 with the axial play been ran? I'm wondering if the tapered collar hasn't been seated against the inner race of the front bearing. Torquing down the prop nut with a prop in place should seat the collar and drive washer. Can't recall any of my BB B-frame Foxes (or my Eagle I or IV engines) having any axial play at the crank. Only my bushing engines have some axial play (which is normal for them).
