Yeah thats a cheap battery tray. The one I want is about $80-100. But it worked at the time when the 3L engine went in and I became broke. So originally the battery was relocated to the trunk during my engine install. After that the idea for the Amps came into play. Yes I worried about screwing the flooring down also, but I used small screws and didnt harm a thing. Im sure others have better ideas for that.
Thanks for the comments.
