90-93 teg spoiler questions

For a christmas present for my buddy, we want to get him an oem spoiler for his 93 teg coupe ls and put it on so when he walks in the garage, surprise. I know more about civic's than anything but i had a few questions simply because i couldn't find any answers on here. First off, are there any spoiler differences between the 4dr and 2dr? Any difference between years? Also, did the gsr have a special spoiler or something compared to the ls and gs models? And last question, If i take off the plastic panel on the hatch, will there be markings for where the holes need to be drilled? Thanks in advance guys!

comeon, anyone?
