I got a traxxas nitro rustler 2wd for my son and I'm new to the Rc world. I bought it used, and it needs some work. It came with aluminum shock towers control arms spindles and new shocks. I'm trying to figure out how to swap all these parts out due too both shock towers being broke and shocks. I got the whole front end off but trying to figure out rear shock tower. I'm thinking the shock tower he gave me was not for the nitro rustler. maybe for the battery one ?
