flipping the mount allows you to use the stock struts. the amount of spacer you use depends on how much drop you are comfortable with(cv angles).
i only made 1/2" spacers, but could have gone mabe 1"?.
i recently made a run and am quite pleased, but i crawl.
i have 31x10.5's on 7"rims. i think you'd have to do more beating and cutting than i did to run anything bigger.
try it. make it work. think |removethispart|@ improvements as you go.
