can buy genuine misubishi but you will get slugged!!!
could get a rear cut from a wreck (evo 1/3, gsr)
danpromote offers a bit of a kit i believe with the awd floor plan plus more
I dont think with his fair prices the freight on top kills it if you can get it locally. Ive got a almost compleate rear end from jspec gsr Thats gotta go pm me if interested
