I’m certain this a common Fiero issue.
Both of my Fiero’s have a quite pronounced gap between the bottom of the tail lights and the black plastic moulding above the rear bumper.

How exactly do you close the gap? Do I need to remove the tail lights? The whole rear bumper?
If you have fixed your gap, tell me how you did it? I’m hoping it’s not a major project.
Oh, and pics are much appreciated. 😊
Thanks, Kit

Hey Kit,

Why not post 'your' gap....?

Pull the taillights and loosen the top (push pins) and sides of the bumper cover (side marker lights, wheel house liner)

There is a metal shelf below the taillight area.

Bend the metal shelf up to restore the desired gap.

Reassemble.

It should take an hour or two to accomplish.

My '84 and '86 are metal, I believe my '87 is metal as well. The design was changed for '88, as my Formula has a plastic shelf.

If I remember correctly, there's some adjustment available with the position/height of the shelf. But yeah, the metal ones could've sagged downwards and might need to be bent back up.

The shelf can be seen below.

Ok, here are two pics from different angles. Sorry, it’s late at night and these pics will have to do.
Thanks guys for the info. My liners are already out so it shouldn’t be too bad at this point.
As an fyi, this is my 85 GT we’re talking about.
Best regards, Kit

My Formula, my son's 88 base coupe and a Formula spaceframe that we have here all have metal shelves.

I wonder if yours is missing or if it was a Canadian model thing.



I have seen different gage metal used in different model years and the base model and 86 and up GT's are different as well.

Another Fiero puzzle....

My '88 GT has a metal shelve too.....

Your photos shows that the lower 'bumper' {fascia} isn't meeting the upper fascia.


olejoedad said, remove the taillights, side marker lights and the wheel well liners
Loosen the sides of the bumper/fascia cover
Bend the metal support upward to restore the desired gap

EDIT for a thought: Maybe I'm wrong but I believe that the lower fascia screws are fasten on the upper fascia with metal clips which are threaded, meaning no 'nuts'. Perhaps you don't have to remove the wheel well liners....?
