Squeaky leaf spring shackles

The only poly bushings I used for resto on my car was the front anti sway bar to k-frame brackets as they were all I could find and like blue says put it on liberally and wipe off the excess after installed. Those Anti sway bar bushings are tough but with lots of the correct lube and 2 blocks of wood with a half round notch in them + 2 clamps they will pop right in the mount bracket.
