The BF bracket with the MGW may be the optimal set up. Because the MGW shifter replaces the entire box and does not have the OEM type snout on the back of it, you must re-use the MGW rear bracket. It is simply inverted and mounted to the BF bracket via an adapter they provide. The MGW bracket has an elastomer bushing in it so provides some isolation compared to the OEM box which is solidly mounted to the BF bracket. Even with the stiffer "track only" elastomer bushing in the MGW rear bracket, there's no additional noise at all in my installation and minimal vibration. It actually just feels like a normal top mount / loaded shifter. Very pleased with the improvement.
