1989 Trans Am / Formula Spoiler

[Motrads]

The Spoiler on my 1989 Firebird Formula is split. Although the car has been garage kept since new, It appears to there is metal inside that is corroded and expanded causing the exterior to crack. Don't know if this can be repaired, or where I can purchase a new one. I see aftermarket spoilers is out there, but the only ones I found so far are made of fiberglass, unlike the original. If anyone else has experience with this please advise me how to best repair this. I want the car to look original.
Thanks in advance for any insight, Mike

Check with a body shop that does fiberglass work. If the metal corrosion extends all the way through the spoiler, you need to replace it.
