That's the prob with the Downey kit. It does not work in the front end.
I'm not familier with how the kit works so I can't give you any tips on modifying it, but I did build my own cable locker for the front that may help with some ideas for modifying the downey kit to work.
I removed the motor and ran my cable from the top where the motor used to be and conected it to the arm that the coiled up spring used to be attached to.
Kind of confusing, but there's some pics on here somewhere.
Let me know if you're interested and i'll repost them.
