nope, 8 speed cassette won't fit, freehub is too short.
remove freehub body, fit an 8speed version, respace hub to the correct 8 speed spacing then re-dish the rim so it's then central as by swapping the freehub body the rim position will be off centre in the frame after the respacing.
remove hub, buy 8/9 speed hub and rebuild into the rim
sell wheel(s) and buy an 8/9 speed set
