gnatsum 12 Report post Posted January 18, 2021 (edited) On my 69 Mach 1 with 351W and C6 automatic, I just replaced the entire front suspension with stock new components and with the Shelby-Arning drop on the upper control arms. I removed the old power steering components and went with manual. The only new component I could not install was the manual steering idler arm. With the long tube headers in the way, I unfortunately can’t feasibly remove the original power steering idler arm. From what I have read online, when you switch to manual steering you should also change out the idler arm to a manual style. With the old PS idler arm still in place, everything seems to match up fine with just a minor modification needed by trimming the bottom of the bushing on the PS idler arm. The steering wheel turns all the way left and right with no interferences. There is no play in the center link connection to the idler arm. Does anyone know specifically if or why it may be a problem to keep the old PS idler arm? Any comments or opinions are welcome. Photos attached.
