rm parts interchangble?

[yellowmagic]

Hi! does anyone know if a 1990 rm250 front hub would fit nicely onto a 1999 to 2003 rm250 axle? Or which years of rm would fit onto the axle of a 2002 rm250 axle, as I know so far the 1999 to 2003 rm250 are using the same diameter axles and are interchangble.thank you!
