The hexes are wrong - those are for the 4x4 SC10.
11/32 hex driver is right - yes it's the same size as the original SC10 but once you convert the front over you need bigger wheel nuts.
If you buy those stub axles you need the steering arms as well as they won't fit the original SC10 ones.

All you'd need on top of this would be the rear hexes.
