Default 2003 Trailblazer: Alternator bottom bolt

Hello!

I'm attempting to replace a bad (read: all) fuel injector on a 2003 trailblazer (vortec 4200). I need to remove the Intake Manifold, but the last bolt is behind the Alternator. In trying to move the Alternator but I cannot get the bottom bolt.

There isnt enough clearance around the bolt head to fit a 15mm ratchet wrench, and these two damn AC lines (see image) keep me from using a regular ratchet. Every video ive seen either skips over this step, or their lines are magically flexible and just move out of the way for them to remove the bolt. Any pointers?

Thanks in advance!
