hi, i need to connect my column shifter to the 4r70w that i installed. i picked up a b&m trans cable bracket. and i know im going to need a b&m cable. question is, anybody completed this. and what parts did u use? what length cable, and how did u attach it. did u change out the sifter shaft in the transmission? i think i can fabricate that easily. thanks pictures would be much appreciated.
