Even without the clutch, you should be able to pull it out of 5th gear to neutral. Put "some stank on it" and see if it pulls out, but don't try to break the shifter in half.
If you CAN get it out of gear, see if it doesn't shift properly in everything besides 5th. Honestly man you probably should just take it to a shop unless you've torn into transmissions before, its not something you want to try as a first time fix job on a Wrangler or any vehicle for that matter.
