clutch cable adjustment

[Rosco]

Ok, well I had it all adjusted perfectly and everything. Pushing the pedal half way would disengage the clutch. But last night something seemingly went wrong. I was driving normal getting used to the new feel and all, and I pushed the clutch in, and pop. OK, so the problem now is that I have about 2 inches of free play, and no matter how far I push the pedal in, the clutch is still engaged. Also when I push the clutch in, I keep hearing the pop noise?? I haven't gotten a chance to get back under the car yet, but you can deffintly tell that the pop noise is coming from the inside of the car itself. I also noticed that the previous owner had installed a steeda quadrant in place of the stock one, and the self adjusting mechanism is still in place. Not sure exactly what I should be looking for inside the car?? And no, there is no firewall adjuster either.
