The EDIS adapter inside diameter is tight enough that in order to tighten the 6mm bolts that hold everything onto the crankshaft hub, a 1/4in drive socket will need to be used.

I supplied six longer bolts for the job. Two of the bolts are longer than the others. I intend for those two bolts to be used to replace the studs in the hub. Being longer, and installed across from each other, those longer bolts can do what the studs did: act as a guide for the insertion, alignment, and tightening of the bolts.
