Double-check the lengths, eye-center to eye-center, of both the pitman arm and the idler arm. I don't know what pitman arm CPP uses; but its length must be the same as the idler arm--else idler arm would need changing to match.

You may even need to upgrade the idler arm to a newer-year style, positioned in tune with the new pitman arm-steering box combo...
