Wheel spoilers on 77-78 Trans Ams???

By tamatt79

Mystery solved, in a day where i am used to seeing bondo and fiberglass, i never thought to look for lead filled holes. We found the holes and were nicely filled in with lead. Old school, whod a thunk it?

This is a Trans AM, the VIN, cowl tag, and build sheet all match!

In the blogs i have been posting on the 17 day transformation, the Trans Am in question along with a 78 belonging to "kirk78400ta" dont have the wheel spoilers. I have seen the build sheet for the 1 belonging to "77TA'' and can verify it is a TA. So can anyone tell me why these cars dont have wheel spoilers? I thought that was part of the TA package.

Correction, the other Trans Am belonging to "kirk78400ta" has the holes for the spoilers. Sorry i didnt see them. Still questioning the 1 my friends are working on though.

More info, there is a RPO code of B97 with the designation of "RR WL Spoiler" on the build sheet.

I have a 77 Formula, and the fenders looked like they needed adjustment, as they stick out past the doors. Trans Ams have vents in the fenders to rid the engine compartment of underhood heat. They adjusted the fenders outwards to acomplish the same thing with te 400 in the Formula. GM did a few things that were not advertised, so no wheel spoilers, does not surprise me. Formula wheel wells had chrome trim instead

Thanks for all the potential info, i am in the same thought that all TA's came with wheel spoilers, and this is a TA, the build sheet was still in the car and it matches the VIN and cowl tags. I have looked but will go back tonight and get under the car and look again for any eveidence of the holes being filled in. There are a few ideas worth looking into, but not much supporting documentation that i can find. I have TA's around me for 15 years now, and own # 1 and # 16 out of the 16 that i have owned. This has been puzzling. But thanks for the ideas, and i will be posting some updates tonight or tomorrow.

There is is a good chance the car was specially ordered without them, kind of like the hood bird was an option. I am a ex-body guy and there is also a chance the holes were welded up and a lot o cosmetic word done to hide them. It is possible.

All of the TA's that I have ever seen have the flares. Mine was purchased original by my dad and it definitely had the flares. If you remove the flares and spoilers you will notice a big difference in front lift at speed. See if this link has any info:

In one of my code books I don't see the RPO B97 "RR WL Spoiler". . . I wonder if that wa part of another package? I'll keep digging...

All Trans Am's came with the wheel flares and rear spoiler. Check the VIN on the drivers side of the windshield. If it's a real T/A it will start with "W87" for a T/A. I'm sure everyone knows this already though!

I've seen one or two T/A's w/o spoilers and flares, I think it was an option thing.
