Rear firewall of .024 inch steel or .032 alum (including package tray) required when battery is relocated in trunk. In lieu of rear firewall, battery may be located in a sealed .024 steel or .032 alum or NHRA approved 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 the body. Relocated battery(s) must be fastened to frame or frame structure with a minimum of two 3/8" diameter bolts. (J hooks prohibited or must have open end welded shut) Metal battery hold down straps mandatory. Strapping tape prohibited.
