67 C10 front control arm bushings

[TonyH]

Quick question guys, I finally got the parts to convert my 67 C10 to front disc brakes. I got new ball joints and tie rod ends and going to replace shocks and springs as well. I figured while I had it all apart I should also replace the control arm bushings. I’ve searched all the normal vendors and have been unable to find the parts. I have found bushings for the rear trailing arms and for the front control arms on 73 – up but none for 67 trucks. I have found the entire shaft. The 1967 Chevrolet Chassis Service Manual shows a procedure for replacing the bushings. Do I have to replace the entire shaft or do these parts generally not need to be replaced. Thanks
