I can take some pictures for you. Jeeps at home though, so I'll need to remember to get out and get them for you.
You can look on bulltear too... Here's a alternator relocation bracket that will bring it to top passenger side of engine instead if you'd like.
Here's a few from a google search:
Basically you have one portion of the bracket along the top that is the "fixed mounting point. Then you have the longer curved bracket on the bottom that has a slot to allow for tention-ing the belt.
My jeep and engine compartment are all together, so the pictures may not be as good as a few of these here. You can also go to google, and select images. I typed in "AMC Jeep 304" and got a couple. You may be able to type in AMC 304 alternator bracket or something similar to get better pictures too.
Let me know if you have some more questions though.
