If I am not mistaken, these are aluminum replacement parts for the stock steel piece. That would be problematic. I have seen people use the stock part, turn it down for a longer shank, thread it deeper and then use the spherical bearing holder. Now you are only changing the bushing material, and it is free. Minor mods to allow the use, but that allows for adjustment of the alignment, so it should be allowed as well. To me the bad part is the material substitution. And the fact that they are red, aren't illegal parts supposed to be flat black?
