I think I was the first person to get their F-4 bracket they sell.
I called up complaining too that the back of the bracket didn't go down to the intake like the original.
I called and they were at least nice enough to go look at a car they had and told me it needed a studed bolt to work. I had one but I didn't use the bracket. I didn't like that it wasn't tapped for throttle clamp bolt either.
My brother ordered a few things from them like a back spoler for a GTO and it didn't fit right. I agree with the poster above if your going to all the work to repo a part is it that hard to get it right?
