Yeah, that. I am too long winded.
Pre 73 B body uppers will work also, think 62 thru 72. (?)

Forget the Volare a arms, they won't work for you.
Just the stuff between the a arms, the spindles etc.
IIRC using the Volare stuff results in hose routing problems, tho not incurable.
I have a set of these, but also had A body stuff, and went with them.
The correct upper a arm you need is for the later A body.
Definitely an upgrade over the older small bolt/4 piston stuff.
