Did a first test on installing the center diff and mount today. I ended up fitting a rear dog bone from a FLM10700 chassis. I've bought a Losi 8ight-T 2.0 (LOSB0085) center diff and a 43T plastic spur (LOSA3560) as I've heard it will actually fit in between the x-braces. The center diff installed right now is a Ofna 6 Spider (correct me if I'm wrong, Joe).
