1996 Magnum 318 alternator question & Mounting battery in trunk

Thanks guys, quite a late reply since it's now all said and done haha. The 318 Magnums been in the '65 Valiant 200 for almost a year now. I did find out that if I had the 318 magnum from a Dodge Ram/Dakota, the stock power steering pump would definitely be interfering with the battery's position from being too high. Unfortunately I had to cut away almost a full inch by (length) 2" of the lip where both ends of the frame are welded to each other so I could obtain clearance between the pump pulley+belt and the frame. So I guess I must have lucked out on the power steering position! However, I didn't luck out on the custom high pressure hose, that was fun to figure out how to get one made. All's going well with the set-up, but unfortunately pulling the 904 transmission out because of a bad input shaft seal, that will evidently be replaced. She'll be back up and running soon, anyways, thanks again!
