EDIT: Almost forgot, you'll have to change the spacer on the left side to bring it down to 130. Also, you should decide which way to go before you build the wheel because it may affect the centering of the rim. Easier to do it just once.
Who. no need to engage in radical surgery such as changing the freehub. google the shimano spec for your hub--it will have the assembly drawing showing each washer and spacer and their widths.
Remove an equal amount of space from each side; sometimes you have to add some back. Now your mtn hub is spaced at 130 like a road hub. I've done this many times. You can too!
Going from 126 to 130 OLD, there is no need to stretch the frame either. If you want to use a 7 speed cassette, first put a 3.3 to 4 mm spacer onto the freehub. Else 8,9 and 10 speed cassettes mount with no problem.
