Jim, what I did with mine on my first Monza was, I put a sheet of paper on the bottom of the spoiler, then I marked the stud locations and cut them out. If you just push them through you will not get the nice crisp hole locations you want, so resist temptation! Now replace the paper to the bottom of the spoiler and mark/trim to size. This can now be taped into place on the hatch and you have the locations for the holes. The studs on mine weren't long enough to pass through both layers of the hatch so I had to open up the inner layer with a hole saw while working upside down (my car didn't have the knock out locations or the holes, I was a kid and didn't have the sense to take it off and put it on a stand/bench or I was too D...N impatient), I didn't destroy it but I would take it off the car for that now, if your car doesn't have the holes "knocked out" already. The spoiler should be taped or glued down, with something like 3M Trim tape, silicone will work, this is what I did as a kid, I would have had to take time off work to buy the tape back then it is much more accessible now and the tape is the preferred method. Remember that you don't want any gaps in the tape as that is how the spoiler is waterproofed so it doesn't leak in through the mounting studs into your hatch(trunk on the others) I am also thinking about putting grommets around the mounting holes to further waterproof the set up, but I haven't checked to see if that will even work yet, (ie: are the studs long enough is there enough room between the spoilers and the hatch to do this without it sitting up etc.). Good Luck and keep us posted on your progress Harry
