A body V 8 K Frame W/swaybar and lower control arms

67 idler arm attachment is a tapered bolt, may also be the same for 68 and 9. I'm not sure...Maybe someone can answer this Q

67 is a one year only design on the idler. I think it can be adapted to work with other years though.

That's a good price, if you weren't so far away... Good luck!!!
