Their the only ones styled like it that I've seen. Have them on my car and yes they do move some but even the torque of my 408 doesn't move them a bunch. With the Eddy Air-gap intake and 1" carb spacer it only has about 3/8~1/2" air cleaner to hood clearance and my air cleaner never hits the hood so they don't move as much as a stock biscuit. Only thing I'd know that's better is a solid mount.
