is there a shifter that cables from the rear?

I am wanting to put a new set of headers on my drag car ( its a slant 6 ) Its running 12.12's and I am close to 11's!!!
BUT to put the new headers on the car, the space the long tubes want to occupy already has the shifter cable mount and cable in the same space.
IS there a shifter for a reverse pattern that mounts to the trans from the rear? That would solve my problem without alot of cutting and welding. Thanks for the help and imput.
