It's pretty crowded in the engine compartment and I wanted to move the battery as far forward and as high as I could, so I built a simple battery mount out of angle iron to hang from the inner fender. I'm not sure if I even checked the clearance between the engine mount and the stock battery mount, but I assume I would have had the same issue as you. The mount works very well. I can post a few more photos of the mount itself if you like.
