There is a difference. The "aero" package and "GT" package looks the same at first glance but they are different.
First is the rear fascia. On the "GT" model - that is all fastback GTs - the molding is rounded. On the far right corner will be a "GT" emblem that can be removed. On the "aero" cars - this is 1984 Indy, 1985 GT, 1986 SE and 1987 SE cars, the molding is ribbed, so it will not match what you have on your car now. You can also tell the difference because on all of the ribbed rear fascias "PONTIAC" is molded into the middle of the fascia below the lights. Rounded molding rear fascias do not have "PONTIAC" on them.
For the front fascia, it is mostly the same from "aero" to "GT" in overall design. However, since the ribbed molding cars were built originally and the rounded molding cars built later, the rounded molded trim fascias you can remove the belt line entirely. You cannot do this with a ribbed "aero" front fascia. The forward most triangle and the back portion between the side marker and the fender are molded into the fascia. Sinced the rounded markers are different from the molded markers in length, the only way to properly install rounded markers and moldings on a "aero" front is to cut the ribbed molding off.
The ground effects along the doors and rockers are the same regardless of "aero" or "GT". You can interchange them freely, but there will be some variances in colors depending on the donor car.
Of note is that the SE cars for 1984 and 1985 will be bumper pad cars (non-Indy for 1984). Since the fastback came in 1986, Pontiac/GM decided to keep the notchback "aero" body style and use it as a 1986 SE. Also of note, the 1987 SE was the last Fiero model built with ribbed moldings. No 1988 model had ribbed moldings.
Here's a very short checklist:
You have a 1987 notchback. You need rounded moldings for the fascias to match the belt line you have now.
