Thanks ABento, I checked both and Straight Line has some that might work, Rare Parts didnt show anything on their website, may have to call. Also I found the Filling Station has a power assist kit, but it requires a modification to the pitman arm, so I need to check it out, says it fits 1947-50.
I left a msg with Straight Line out of San Jose, got a call back and a guy there is willing to assist in selecting a new box..
