I was on your side until I put them side by side, they looked like the standard extensions to me too.
After looking at other rear quarter extensions pictures I have found several non grabber extensions with the dimple, just to throw this out there for consideration is it possible that the dimple was for models that had the option to have the trim put on them or that it was a year thing. I will say that all the grabber extensions I have looked at did have the dimple so that is good to know. My car is in storage so I will have to look at it to see After looking at the buyers pics again the only thing that would make me believe that they are in fact for a grabber is the point at the very top. Here is just one example that I found of non grabber extension with dimple http://www.ebay.com/itm/NOS-1970-19...ash=item1c6048e0ef:g:B4IAAOSwCypWpN9v&vxp=mtr I hope that he did get the grabber extensions
I kind of think that the one in the eBay auction above is a Grabber extension and the seller doesn't know it.....as well as the ones in the very first post.
I think they're Grabber. First pic show's the dimples that line up with the bottom edge of a Grabber spoiler. The tops on regular Extensions slope down with the lines of the rear of the car. Grabber extensions see barely more than level to the bottom of the extension.
I learned something from this as well but will be looking at every rear quarter extension I see for awhile. This newly learned fact will will come in handy at swap meets, that is if I ever see Maverick parts at them
if the pictures hadn't been as skewed as the were.. it would seem to be pretty easy to notice that upswept angle compared to the flat mounting surface, right? And if that isn't obvious when it's sitting in your hand.. it sure looks like those tell-tale dimples would then become the dead giveaway.
