I have this bracket with my Revision 2 (not race shifter) MGW shifter and recently added the MGW stainless bushings in the shifter support arm. Apart from putting in the Magnum, this combo is the best bandaid one can get for this transmission.
I started with just the MGW, improved, but still not perfect, Then added whiteline transmission bushing insert, more improvement but still not perfect.
Added this bracket with MGW bushings and it's about as good as it can get.
I track my car and this combo not only got rid of some of the NVH now that the shifter moves with the transmission shifts under load are greatly improved. And the rest of the time shifting is like buttah!
I'll be running this until my transmission blows up and it's time for a Magnum.
