To get the safety of a fire extinguisher in the car,
while keeping it hidden yet easy to access, I purchased
a HalGuard Model HG100C (chrome).
I bought it from someone on eBay at a really great price.
mounted it up under the dash, completely
hidden but within easy reach. The
bracket it came with was sized perfectly
to line up to existing screw holes under
the dash, with some minor modification
to the bracket itself. So I didn't have
to drill any new holes into the car.
If anyone has any questions about any of this, feel free to send me an email!
