This is a question to all 61 - 64 F100 2X4 owners, at least in this case, 1964:  I'm trying to figure out a lasting replacement for the front spring, front shackle bushing. This is the 7/8" diameter bushing in the frame. My thoughts are to see if a urathane bushing of a larger size could be reduced in size (sanding/filing?) to work for this application. Would need to keep the side shackle bars gap solidly maintained but allow the upper bolt to rotate in the bushings. Nothing is available for that under designed 7/8 front bushing. Removing the riveted upper shackles from the frame and boring to a larger size may be the only option.  I have to replace both bushings once every summer. I even made a tool consisting of a sleeve and threaded rod which does the job quite quickly but would rather design something that would last. Besides all the vertical pressure, there is side to side and twisting moments common to a straight axle. As mentioned on a recent thread, the replacement rubber bushings aren't what they used to be. Thanks in advance, JEFF....................
