Slack in Clutch Pedal

Hey guys. The other day I was driving down the alley in my 2000 GT and as I pushed in the clutch I heard a slight pop sound. I suddenly noticed that the clutch pedal had more slack. Now I can push the pedal about 1-2 inches until I start to feel resistance. As far as I can tell the clutch still engages/disengages in about the same place and there doesn’t seem to be any drivability issues. I tried the clutch adjuster where you pull the pedal up with your foot but it didn’t make any difference. Does anyone know what’s going on here? Thanks.

anyone?

Is the stock clutch adjuster located on the firewall?
