I can't find specifications on them as far as lengths and taper/bore sizes, but there are different listings for pitman arms from '63-'72. Te part numbers in Moog are; '63-'66 K6086, '68 w/power steering K6131, '69-'72 w/power steering K6131. '69-'72 w/manual steering K6130. The last two were also used on G series vans '71-'82. I'm not sure why there's no listing for '67/'68 w/manual steering.
You might also verify that the idler arm is correct/matching to the pitman arm. They should be the same length. For '63-'66, the number is K14, for '67-'82, it's K6096T.
