this is the one i bought: http://www.taylorvertex.com/hp/index.cgi/BatteryBoxes
they state "Complies with NHRA Rule 8:1 - battery box Required by NHRA when there is no firewall between driver’s compartment and battery".
browsing NHRA: "At present, Moroso is the only company which offers an NHRA accepted plastic battery box, part number 74050."
the actual rule (2004 rulebook):
"8.1 BATTERIES
All batteries must be securely mounted. Batteries may not be relocated into the driver or passenger compartments. Rear firewall of 0.024" steel or 0.032" aluminum (including package tray) required when battery is relocated in trunk. In lieu of a rear firewall, battery may be located in a sealed 0.024" steel or 0.032" aluminum or NHRA-accepted poly box. If sealed box is used in lieu of rear firewall, box may not be used to secure battery and must be vented outside of body. Relocated battery(s) must be fastened to frame or frame structure with a minimum of two 3/8-inch diameter bolts. (J-hooks prohibited or must have open end welded shut.) Metal battery hold-down straps mandatory. Strapping tape prohibited. A maximum of two automobile batteries, or 150 pounds combined maximum weight (unless otherwise specified in Class Requirements), is permitted. Maximums may vary according to class requirements."
also a good link to read, lots of detail and explanation: http://www.hotrodders.com/forum/roll-bar-install-advice-73625.html
