I have no idea what's on the other side of any given panel in my car.
That's why you drill the holes.
Didn't anyone ever tell you that experience is the best teacher?
Seriously though, I use a .30 cal ammo can with a homemade ammo can lock,
and a pair of handcuffs to hold it to the seat frame. Good luck getting it out, I have a hard enough time and I know just how to hold my mouth right to get it to work.
All things being equal, fat people use more soap. (I know I am one.
) High speed, low drag does not even come close to describing ME.
