You said camber bolts? Do you mean camber plates?
if you are running the Steeda camber plates than it’s the plates. I had them on mine, changed them to the ford performance ones and noise is gone.
Not that specific one, I tried the speed form and not a great fit.
what has been said is that the BMC one is the best fit for the convertibles.
you can search the forum and find a ton of info

Unfortunately it is, I looked it up on the ford parts and in is he new part that they seem to be using.
thanks on the aftermarket part, I’ll take a look at that one :rockon:
