I've heard the same thing, but from several different companies over the years. It would be best to call before ordering a spool without axles. That being said, I raced by car with a Dana, Strange spool and shortened stock axles for a long time. When my axles started to twist, I replaced them with Moser axles. Both fit fine. I now have a Dr. Diff spool. My Moser axles fit nice and snug.
