I'm not sure there was not a change in the upper arm in 67 that carried thru to 1974. And it's possible MOOG didn't tool up for an obscure part with only a two year application.
You know Ford never made replacement bushing for these arms, if you needed new bushings you bought a complete new arm (serviced as an assembly).
Back in 1999 I needed to go to Rare Parts for the upper bushings and had to do the same thing for the P-Code restoration when we did the chassis back in 2006.
I would be nice to hear from someone who has actualy used the K8136 Bushing kit in a 65/66 Galaxie. ww
