Partially because I'm intrigued, partially trying to help you guys out, I went and took a Pano Series of pictures down below...from driver's left to passenger right:
So first thoughts...my battery is def on the right (above) picture. I checked in the trunk and that's where it is, so unsure where AH3's battery is, but should be behind the metal heat shield you see on the far right.
Additionally, though I'm a big believer in how awesome it sounds, but seeing how rusty it looks at the welds after only 1 winter (albeit, CT had nearly 40 inches of snow in one weekend, and they were spraying salt on the grounds), I'm going to venture to say that it might be better to wait for an aftermarket alternative that has higher grade steel?
I don't care if it rusts through since I'm golden for 6 or so years, but others might...
