Spindle ID

Well, let me Edit post #2 if i may.
I had these pictures in my other computers files.
To help out further in this question and answer, the op spindles aren't C body ones like i thought.
And they also aren't F body, Aspen & Volare spindles either.
In the first picture, Aspen & Volare spindles and on the left, and A body, 73-76 spindles, on the right.
And the other pictures are what C body spindles look like, just for reference.
Hope it further helps out, here.

The early tall spindles ('73-4 or so B-body) look like a '73-later B/E spindle in the area where the caliper bracket bolts on but they are dimensionally the same a F/M/J spindles otherwise.
