Stuck on V-Belts: ALternator bolts frozen and tension bolt broken

[okyoureabeast]

I am nearly finished with my water pump replacement, but I am stuck on the belts.

The alternator bolts are completely frozen in place. I've heated and soaked them in penetrating oil.

I eventually got the bottom bolt to break free using a vice grip and mallet

How the heck do I get to the three bolts in the rear? I have the turbo in my way.

Also the bolt that adjusts the tension is broken. I feel as if this should be significantly easier than this appears to be.
