my opinion also. and even when installed properly, the chintzy brackets bend and move because they are not properly supported and made of cheap [my opinion] material. in all the change backs i have done, all but one was installed correctly. i believe these are just a GM design sloppily changed to fit mopar applications without any thought to correct ratio differences or bracket inequities. i'm glad some have had success and are happy with the function of their installations, but i have changed too many back to the correct factory setup, and am not impressed with the design or the component quality of the locar components.
