We are talking about a CJ or Wrangler right?
With a Wrangler or CJ its easy to take out the carpet. Everything snaps in with most Wranglers and the CJs velcro.
That's really fucked up. That's one of the bad things about driving a convertable. I had one of my doors taken off my Jeep and it was used to break into cars alongside the road at a party. I found it in the windshield of a new BMW. They also stole a bunch of CDs. My CDs should have been covered under my homeowners policy, but American Family fucked me out of that. I installed an alarm with two motion sensors in it the next day.
