RE: my nemesis weight
If you decide to use the telescoping outdrives on the Nemesis, the bearings need to be changed as well. The bearing that is standard on the Nemesis is much larger than the one on the Genesis.
If you have a GST 7.7 and you want to change the outdrive for rear to the telescoping ones, you will have no problems as the spacer for tranny case is already there (part number GS286). But you have to do some grinding to get the clearance. I am not sure on how much, as I have not done the telescoping mod to the rear driveshaft of the GST/Nemesis/Genesis trucks.
The reason for this is that the GST and Nemesis come with the Metal to Metal brake systems stock so they use a different tranny case, hence the need for the spacers.
If you are trying to convert a Nemesis to use a complete center telescoping system, it would take me a little more time to try and compile a list of parts that you would need. Hope this helps.
