9/16" tie rods, Fast Ratio arms, etc...

It is a funny thing....The TTI instructions clearly state that the FR arms do NOT clear in my application, a 1970 Charger. I had a Fast Ratio Pitman arm that a buddy bought for his Challenger so I held it up to the steering box. It looked like it would be fine so I ordered a Pitman and Idler. They both fit with at least 3/4" clearance. Everything I have is in the stock location so maybe TTI was just covering their ***?
