What Is the black gfx looking thing? I know its not stock GFZ for an 84 and where can I pick that up from?

 

That IS the GFX front spoiler for the Optional Aero Package for 1984. Kind of hard to come by, but most definatly a stock part.

 

Do you know where I can get the complete aero package?

 

I'm working on that right now myself, bud!

All I can say is that this year is a very hard year to get GFX for as it was only used on a limited few 1983 Daytona TAs and was an ordered option for the TA in 1984, and not all 84 TAs got the Aero Package, limiting it even more.
Now if you were to look for the 85-90 GFX, you would find them alot easier to find.
You would have to get new front and rear bumper covers to complete the package.
So, you would have to REALLY want the 84 Aero Package, to go through the pain of trying to locate all the parts. Or Update your car with the 85-90 GFX, and enjoy.

I've tried E-bay, junkyards, and the classifieds. The 84 stuff just doesn't come up that often.

Good luck,
Leon.
