    just fit a spacer behind the 7spd cassette, on the 8/9spd wheel. The wheel alignemnt will be fine.

    LBS will have the spacer. Or wiggle/crc etc.

    An old bottom bracket lock ring is the same width as the spacer needed
    Just file off the threads..
    Not a lot of people know that. :(
    And probably don't need to. :)
