The front driveshaft in the GST is plastic, the front driveshaft in the Nemesis is steel. The center diff and diff cup reqiures the use of some spacers and extra screws, however I have heard the the newer GST's already have the bulkheads so all you will need is the front transmission, drivecups and the steel drive shaft. I order most of my CEN parts from
www.customrccars.com. Give Ryan a call he will help you out and hook you up with what you need.
Can someone tell me what parts/part numbers I need to buy for the center differentiial in my GST to mate up with the nemesis front propeller and diff. I know I need a new dif cup, but which one? and what else is required? Thanks
