Here is my Idler Arm Conversion. This is a 67 6 Cylinder K Frame that I modified to go with my Twin Turbo V8 Build so there was no going back and getting a Newer K Frame. In the process I found out the the 67 Idler Arm is a 1 Year Deal and $$$ boookoooo expensive $$$ so I converted all the steering over to 73 & Up.
I got New Lower ball Joints, Idler & Pitman Arm for $106.00. That is about 1/3 the cost of a NEW 67 Idler Arm........ I will be getting some Firm Feel 11/16 Solid Sleeve Tie Rod Ends also.
