Nice! Not much savage left to it! Did you use everything from the hinge pins on out? Those carriers don't appear to be HPI either. Did you have to mod the arms or shim them to fit? What shocks are you running, seem short, but could be just the mounting point on the arms. I have so many questions!?!?!? Got a build thread?
I just installed a new 9T pinion in my front diff... landed hard off a jump and took a tooth out. I stopped before the ring gear was damaged. Wasn't able to find any pinions alone listed on ebay, so ended up getting a sintered 29T ring gear and the pinion for $22. I guess beggars can't be choosers. lol
