I don't have the parts #'s in front of me, bit the kit comes with the v1. The v1 motor mount is seperate from the layshaft mount, and has a center support for the topdeck. The v2 has motor and layshaft mount in one solid piece, with no topdeck support. Though it is possible to combine the two to retain the center mount.
The combined setup is what I've been running lately, though I've been suffering with a little too much rear grip on entry/exit.
