Don't know on the nemesis, or the parts, but when I had me LE transmission apart to fix the shift lever, it seemed like the only difference was the GS086 gear. That when the shift lever was in forward that it engaged the internal shifter and for reverse engaged the GS086 gear. But then again I don't have the nemesis, but let me know cause I might upgrade to the alumi GS008 transmission and put reverse in it.
