I'm not sure if the GS010 is the part number that you are looking for, that is the part number for the hub and knuckle. I believe GSS10 is the pn for the Nemesis heavy duty drive shaft and diff outdrives. I just swapped in the entire Nemesis diffs into mine which will allow you to get rid of the telescoping front shaft as well. See the post titled "Help me build the ultimate CEN GST 7.7 basher!" in this forum and that should answer all of your questions, hope this helps. [8D]
