Hello, I have a 65 Ranchero. It was born a 6 cylinder 3 on the tree with manual steering. It's now a 302 T5 power steering. Not sure all that matters related to the idler arm. Similar to the picture below, where the idler arm mounts to the frame, you can see there is bushing exposed. It's like the bushing is too tall for the 'arm'. When I jack the car up and wiggle the wheels, that arm rides up and down on that shaft. Everywhere I look, I am told this is the right idler arm (Moog part K8106), but I have seen other pictures where there appears to be a bushing (like a thick washer) on that takes up that extra space. Not sure I am making sense. It just does not seem right that I can move the wheel and see the center link make that the 'arm' move up and down on that shaft.
