the toe-in is TRULY very important.
During my trial & troubles with the original 5/32 struts, I had toe-in & toe-out. Both caused problems. When hte wheel was toed-out, the strut would bend outward as the wheel tried to roll in that direction, until enough force was generated to jerk the wheel back in -talk about a funnny looking taxi.

I paid close attention to getting the flat spot on the strut, for the set screws to the retract unit and the axle, ground at right angles to each other. Then installing the axle and having the toe-in straight is easier. I just aligned on the mounting screws for the retract unit into the wing and that seems close enough.
