yeah, im the owner of that shinny hunk of junk!!
I have a pic of the back but it is WAY to large. however, i can assure that it isn't a GTO spoiler... i don't think it would look good on a f-body. The spoiler is a RKSports Roadster Spoiler.
hope that pic went through!!
you can find it here:

its a nice spoiler, a little different than the regular SS style and not too high as that other wing type of spoiler. Its not a bolt-on, it comes with VERY, VERY strong adhesive tape (seriously, very strong stuff!!) All you have to do is line it up on-top of your old spoiler and your set. With my vert., the spoiler does flex a bit in the center and slaps the stock spoiler under it at over 120mph... not a huge problem but a bit hair-raising!! I ghetto'd some little tabs under it and problem fixed... not perfect but ok for now.
