Hey guys,

I have all the quarter panels/bumpers/ground effects for the "lower half" of a gt (I want to leave it a notchback but have gt ground effects). What parts do I need to switch the front and rear bumpers out? I know I'll need the gt egg crates but I'm not sure what else I need to get a hold of and are there any holes that need to be drilled anywhere? Thanks in advanced everyone

wheel well liners on front are different I know not sure bout the rear and the splash guards around the radiator and egg create should be it I believe... You will have to drill holes to attach the lower door moldings and piece for lower front fender...

it would help to know the starting vehicle. You really want what is called the AERO package.

You'll need the rocker panels also. Not sure if that is what you menat by "ground effects" above.

Starting is a 1987 notchie 2.5

Yes rocker panels lol I went brain dead when I was writing and could not for the life of me remember proper terminology.

Jaski could you elaborate more on what the aero package is please. I did a quick search but I don't understand if that is the same or different from a gt as far as body panels are concerned and if I'll be able to use parts I already have. Thanks!

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.

"Aero" cars with ribbed moldings.
- 1984 Indy
- 1985 GT
- 1986 SE
- 1987 SE

Rounded molding cars ("GT"-style moldings)
- 1986 GT
- 1987 GT
- 1988 GT

The problem with saying "GT" is that the 85GT has the AERO panels.

I know I hate that nomenclature when referring to the body panels that way, but so many people refer to the rounded panels like that as "GT" I've just kind of called it the same over the years.

A really detailed on-line "spotter's guide" would be REALLY nice to have when questions like these arise.
