i had read somewhere that relocating the battery to the back was dangerous since it's close to the fuel tank, in case any fire was to start or whatever. i read that someone used a kit supplied from summit racing as well. i was thinking of doing the same, but i'd rather build a custom box of some sort to hold it there, then maybe a "Z" tiedown bracket to clean it up somehow. was it difficult to do at all?? anything tips or pointers?
