Da rules:
<<3.14: Battery: All batteries must be fully secured via proper, purpose-built battery brackets, battery frames, or sealed battery boxes. Zip ties, bungee cords, duct tape, macrame plant holders, and other lame workarounds won't cut it. Positive ("hot") terminals must be in a sealed battery box or covered with insulating material.>>
Says battery must be secured by bracket or batt box. That's a section 3-safety rule, so budget for the box is open, IMHO. Also, as the OP pointed out, safety rules required buying new long batt cable to install interior master switch. Now we have enough cable to move the batt from the front corner of the car to the pass. floor.
Of course right about now is the part where a member of the Lemons Supreme Court punches me in the throat and says "Judicial interpretation is OUR bailiwick, sucka!"
