20b ...We ordered the optional billet band clamp (PN BB100P, $87.95) and flat-surface mount (PN BMF01P, $48.95) for cockpit mounting and quick access. NHRA-legal rollbar mounts are also available. Many Roadster owners place their fire extinguisher under the dash at the front of the transmission tunnel. It's a nice place visually, but we were a little concerned about access in an emergency situation. Eventually, we opted for between the seats in a horizontal mounting plane with the quick-release pin facing up. A quick yank of the pin straight up and the extinguisher is free to do its job. We can quickly inspect the pressure gauge in this mounting position as well.
