PlanePower Standby Alternator Installation

[rkbrown819]

I'm trying to install a PlanePower standby alternator on the Lyc. IO-540. I have tried every tool in the toolbox, but I can't figure how to access the nut on the lower inboard stud to tighten it. Has anyone done this? I'd appreciate any advice from you mechanics more skilled than me, which is probably almost everybody.
Thanks,

You need to make yourself a special wrench made from an open end wrench bent into an s shape It’s a pain, but doable

Would a crowfoot work?
