TA Steering Box w/stock pitman/idler arms

[ChallengerGreg]

My steering has been wonky and I’ve discovered that I have a TA(fast ratio)steering box, fast ratio pitman arm and stock idler. I believe the pitman/idler is throwing off the geometry. Unfortunately I will run into exhaust clearance issues if I use the longer f/r idler. I’m seriously considering installing a stock pitman arm. Yes, it’s a significantly more expensive part but I won’t have the expense of resolving the exhaust interference issue. Will using stock pitman/idlers with a f/r TA steering box create problems?

 

[Challenger RTA]

Yes

 

[ChallengerGreg]

Yes

Any idea what it will cause?

There is a moog replacement C body idler arm? I think the number is . K7014 I have to check on that or someone might know that number. Checked K7014

Both arms have to be the same length.

Both arms have to be the same length.

Just to be clear I want to put a replace the f/r pitman arm with a stock one which will be same length as the existing idler. I should be good to go in my opinion but don’t know if it will be a problem since I have a f/r TA steering box

 

[Challenger RTA]

Yes that will work. Check the pitman arm's shaft diameter .

The pitman arm you have on does it have fast ratio on it?

Yes , that the one.

Yes that will work. Check the pitman arm's shaft diameter .

I checked 1 1/8”

Pretty sure the idler arm is the same, the T/As didn't get a longer version.
Just the pitman is longer.

A little more info that might be of help.

This is another "retro post". This was work I had done prior to putting on the wider tires. The problem was that I had my power steering box rebuilt by Steer and Gear, to the TA specifications. I purchased the longer pitman arm and the longer idler...

Call Firm Feel, they were extremely helpful when I needed a pitman arm for my 69 383-s fast ratio steering box. Only they knew what I really needed. U.S./Canada 1-360-546-3633

I called them and they were very helpful

Big block car? On my brother's 70 R/T he added aftermarket fast ratio pitman & idler arms, the only issue was the passenger's side headpipe needed a little tweaking for clearance - I forget if it was just a matter of dinging the headpipe a little or if he took it to an exhaust shop for them to section in a slightly different piece, but either way it was a minor thing. I have Proforged fast ratio arms going on my R/T build and right now the idler clears without the grease fitting installed but I'll have to do something similar.

Be wary of the technical advice given.
Use the idler for a 70 fury to correct the geometry. If the fury idler hits the exhaust you have other problems!
