Another lets play "ID these parts"

I have a couple different Idler and Pitman arms from an A body.
One Idler the smaller one on top in the coming picture has a # on it---KR8 E39
The larger Idler has MC133 E 2044 on it.
The larger matching Pitman has 4-233 on it.

The guy I got these from told me the larger ones, which were on power steering.
I don't know about the smaller one , not hooked to a gear box.
Anyway the guy told me they are both Abody but the larger are quick ratio.
Can anyone confirm that or know what these are exactly
These are all ‘73 and up parts. The centerlink would mount from the bottom, nuts facing down. Pre ‘73 the nuts would be facing up, centerlink sits on top. I think the top one is a stock factory part, the others may be aftermarket, fast ratio, like shown in the other thread.
