64 slant 6 4 spd to v8 and 9 to 10" drum questions.

OD of pilot bushing is .940. The upper and lower control arms are usable on your '64. There are differences in the lower control arm mounting studs over the years so I'd measure and compare before just using. In addition to the center link you won't be able to use the pitman arm (at steering box) or idler arm on opposite side. While they may attach to your steering box and "K" member respectively, they have a different shape and will likely place the correct center link in an incorrect position if they even mate to it.
