VIN# locations

nothing in the trunk under the gasket or the drip rail. nothing on the speaker shelf, and the only thing on the radiator support is 2 areas that look like they had pins ground down, that are a little more than 4 3/4" apart.
my big concern is the paperwork i found in the car. it has the owners manual etc. and in with it is the warranty slip and a "vehicle stopping distance" slip. both of these have a different VIN on them than the car.
