Under the dash, where you installed the pedal assembly. You should have a white gear on the assembly (I think it's on the right near the brake pedal - don't remember). It's where the clutch cable slotted into, you must have seen that?
oh boy, I don't remember that part. It was midnight, I was drunk, pissed off and used a hammer lol. But the thing works like a ratchet. Pull the pedal all the way back and press down. But do a search here on "clutch" or "clutch adjustment"...
