Stock Firewall/Floorboard thickness
Anyone know how thick, gauge wise (16? 18?), the stock firewall and floorboards of a GM Metric car are? Making a new one and it is supposed to be equal to or thicker than the stock one. Thanks

If your running UMP rules.
The floorpan and firewalls must be stock in appearance and be complete on both the driver and passenger side of the vehicle. The front firewall must be a maximum of 12”-inches behind the rear edge of the engine block. The floorpan and firewalls (front and rear) may be repaired and/or fabricated, but must retain stock appearance and stock material thickness. The minimum thickness for replacement material / patches on the floorpan will be .060” with the maximum being .125”-inch magnetic steel.

Local Rules
We don't run UMP, but that gives me a ballpark range to go with. Thanks.

I have been trying to figure out the stock thickness, not stock+undercoating+paint+rust layer. I think stock car is right on the rough size. Imca and our local tracks mandate 0.049" replacement. I think ump does the 0.060" to discourage replacement. I have a feeling stock is 0.049 or slightly less. One needs to sandblast a piece and measure it, I never have had time to.
