67 f100 2wd steering box

[67 short box]

just wondering why the 67 steering box and pitman arms are different than 68-72 years.
manual steering. thinking about later on if I need to replace either. I think I know a place in dallas that rebuilds the boxes, but I don't see a pitman arm available anywhere. lmc of course has 68-72 boxes and arms. but not 67. can the 68-72 be used on the 67? thanks..

Are you referring to a manual or power steering gear box?
