I have one of these exact spoilers directly from Brazil. They are very rough fiberglass so they need a good bit of finish work. You may have seen the post on another thread from the guy in Florida who is from Brazil who mentioned that many parts from Brazil are hand made and therefore the quality is often much lower than they appear in photos. But if you want it, I'm not going to use it so if you're interested, PM me.
They make those for the second gen. camaros. I would like the spoiler on the shelby de mexico mav...kinda looks like the spoiler shelby used on the Gt-500's I'll be making one out of fiberglass.... when money permits
Yeah, roughly 74-81... They also put them on all the H-body hatchbacks. My dad's 78 Monza (glorified Vega) has one just like it from the factory. IFAIK that spoiler is a GM creation all the way. Edit: Forgot about the Firebird/TA as well. "East bound and down, loaded up and truckin', we gonna do what they say can't be done..."
Trust me, while the maker in Brazil may have used the GM spoiler as inspiration for that spoiler, it is a rough, hand-made spoiler, but it does fit the Maverick body contours. I believe the Shelby de Mexico spoiler was made on the fiberglass trunk lid. I have a close-up photo of a person standling by it (at the same auto show that all the pics on the internet seem to be from) and it's not a separate piece. It's molded into the trunk like some of the Shelbys mentioned. When I got the spoiler like the one pictured above, I was trying to get one of these. It is a separate piece like our U.S. versions, but a few inches taller. I've never been able to get one and have been told it was probably hand-made by the owner.
If you go to Youtube and put Ford Maverick in the search...you will see dozens of videos of Brazilian Mavericks. One I saw yesterday had the "Camero" type spoiler on it.
