Do yourself a huge favor and throw away the bolts that come with most of the ankle detail parts. It’s virtually impossible to quickly assemble the ankle with them. I have small hands, but even I had a problem getting in there. Instead use hex head cap bolts in place of the Philip heads.
Like an idiot late one night I suffered through putting my ankles together before C4 with the original bolts. I even bought one of those fancy right angled screwdrivers – it did the job but it’s still incredible frustrating to use. It’s funny how sometimes you’re so close to a problem that you’ll go down the totally wrong and longer path for a solution. In this case the right bolts and a small wrench did the job so much better.
I’ve also swapped out a bunch of bolts that came with the JAG drive system. The originals work fine, but again it’s hard to get into the tight space to adjust things.
