Where to put new driver's side junction post

I'm getting into tidying up some wiring and I'm going to install a junction post on the left side. Between the washer bottle and core support maybe, pretty much straight across from the junction by the battery , not a whole bunch of room there. Or on the core support on that vertical piece left of the rad.
What do you guys think?

I'll also be upgrading the wiring from the alternator to this new post and across to the battery. My headlight relays are in that box on the core support so they'd get power from the new post , too
