New Fast Ratio Steering Linkage Kit $239!!!!!!!!

Im running a small block 360 with TTI headers on a 67 Valiant, the headers go above the drag link. Also what ratio would this change mine into with a standard 24:1 manual box. I have upgraded the front end to 73 disc break set up which included tube upper a arms with larger ball joints, spindals, lower control arm/ spindale tie rod connection all of that stuff, would it possibly work for me ?????. Thanks. One other thing my K frame is a later model v8 frame that has the through bolt idler arm mnt. to the k-frame. (if that helps in figuring out if I could use it)
