This last spring I installed a Firmfeel pitman arm and idler on my 71 RR. I have the Firmfeel system throughout my suspension . I'm running their CR power steering box. I've only driven the car several times since then. Yes the pitman is not indexed. The test drive after installation was interesting. Doesn't take much effort to change lanes on the freeway. Didn't really notice any change just from driving the car on the street except when we did the Friday cruise at Springfling. Mullholland Drive was a lot of fun. Oh, only issue is the idler arm has some clearance issues with the driver side TTI exhaust. I still need to run it up on the alignment rack.
