2007 chevy trailblazer_ls
haven't noticed and new updates from the OP and was wondering how things were going. i have been giving this subject some thought and would like to try it myself. personally i think i would go with a manual tranny with maybe an atlas 2 t case and replace my rear axle with a ford 9 inch. not even sure if that would work or not. either way, am hopeing there is some progress on this subject from Spot u 3. hope he didn't give up on it.
