1976 duster spindles same as 73???

I might be picking up a set of disc brake spindles and upper a arms from a 1976 plymouth duster. I was wondering if they are the same as a 1973 duster? Or are these like the later volare type that are a little different? If someone could shed some light, that would be greatly appreciated.

They are the same, I got mine off a 75 and they are on my 69 Barracuda.
