Okay, I'll look into those axles is all else fails. Might try to modify them, whats the worst that'll happen, I ruin a $75 axleabsolutely can be possible ... whether is worth it ... the cast metal might not sustain such surgery ... but I can see how you can cut a section off the straight part from each end ( find a clamp, jig or braze to hold together ) and cut down the axle shafts as well shave the end to key-into the locker. Likely not worth all that work... hence a lot of builders use the readily available mst cmx axles to keep the track narrow.
