get your head in under the dash and look at where the clutch pedal might go, you will see some furry material circle behind a black plate, get that stuff out and the grommets past that.
or just look to the right of the brake booster from in the engine bay for the oval looking grommet.
have fun getting the grommet back in. (you need to remove the grommet to cut a hole, because its about 8mm thick)
