tranny kick down

I am finishing the install of a 318 with a 904 tranny. Number one is that the cable I went to is too long and had to modify so that my 4 barrels would open . I need to find the right one .
#2 is that I have a single bar kick down for the 904 , but something doesn't seem right , maybe the travel . is it suppost to be a three piece set up, or do i need to work with it some more....Thoughts??

Thanks Dan
