I dunno, that's the way OME did it (all poly bushings, OME SB43 kit). Fixed end spring eye is 40mm, the bushings are 40mm OD, 19mm ID and the sleeve is 19mm OD and 14mm ID for the bolt. I was wrong, the fixed end bolt is the factory bolt, not greaseable.
In the back I'm running aftermarket shackles with greaseable 18mm bolts at both the frame and spring, bushings have 30mm OD and 18mm ID, no sleeve necessary.
The factory used sleeved bushings at both ends of the springs with 14mm bolts. The frame side shackle bolt was 18mm.
