The CPP bracket for the dual MC I have, not using a booster, fits very smoothly between the two crossmembers without any interference. It puts the dual MC pretty close to the same place the old one was.. it IS further back and more towards the tranny, but very close. Its the latest bracket, so not sure unless you have a booster. Then it makes sense. Why I decided to roll the dice and see if my lead foot can stop the truck without a booster.
