If you look on the first page, BillaVista lists the differences between the 60s. One of the diff's is how the brake spindle etc goes on. It's been a while since I tore into one, I forgot too!!! This help??
7) The Chevy/Dodge caliper mounting bracket bolts on AFTER the spindle, as in knuckle-->spindle-->caliper bracket, whereas the Ford mounts the caliper bracket between the knuckle and spindle, as in knuckle-->caliper bracket-->spindle
