Another lets play "ID these parts"

[RAT ROD AL]

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

The factory never made "quick ratio" (longer) steering arms for A-bodies, so it's not that (they made quick ratio boxes, instead). They made a quick ratio pitman arm for E-bodies, but never made the matching idler arm, to the immense frustration of the Mopar Trans Am racing teams.

They are all for 68-up, that you can tell. Maybe one 68-up A-body idler and a set for a E-body or B-body?

I thought 67 was a differant length and 72- 73 was the flip over year for the center link mounting.

There are a few aftermarket examples of longer, fast ratio pitman and idler arms. Firm Feel and Hotchkiss sell them. I believe PST did also, but I don't see a listing currently. Proforged makes them, and they've been on Rock Auto recently, but they're not listed now. Covid shortage? Proforged is on Amazon, but I don't trust their application guide.
Matt Ross at Firm Feel told me their arms are 1.5" longer, which would have hit my stock 340 exhaust. Maybe this will help.

I just bought the Proforged units from Summit, I can take pictures when they get here if necessary...

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.

All correct.
One more thing to look out for is the size of the sector shaft holes in the pitman arms. It seems that even though '73-up power steering used the large sector shaft, some of the aftermarket fast ratio pitman arms have the small, one inch hole.
To get some aftermarket fast ratio arms to work can require using a hodge podge of parts, including the '73-up centerlink, and the '72-down power steering gear.
