NHRA Rulebook? Confused!

As archaic as it is, I believe that the rule is clear. There is no sentence #1 and sentence #2 applying differently to different situations. The replacement material that they refer to is between the BODY and the new frame rails only. All other floor must be the stock flooring from the tunnel to the new frame rails (center of the floor, out) This applies to the trunk as well; refer to page 273; general regs 7:5 (SS trunk floor). That being said, I have looked at several SS cars in the last couple of years that have complete replacement floors from the rear of the front seat mounts to the taillight panel which seem to pass tech without a problem. I dont know what the criteria for forgiveness is but it seems that a high quality replacement floor that is made of the accepted material (same guage sheet metal as stock) and is in the stock location, is OK with NHRA. The rule should be re-written if this is the case. The rule is especially stupid in the trunk are on some cars; a rules clarification would promote much nicer cars and would serve no performance agenda.
