Front AND Rear Spherical Bushings?

[hardline_42]

I'm in the process of designing my rear suspension and I've come across some conflicting information (at least it seems that way). I plan on using a custom rear leaf setup with fiberglass leafs (say what you will) mounted inboard of the frame rails with the front mounts angled in further than the rear and modded Herb-Adams style. The rear shackle will be replaced with a slider. The confusion comes up in bushing selection. The front spring-eye will definitely have a spherical bushing in it ( http://www.suicidedoors.com/SuperPivotBarEnd.php). My understanding was that for best handling the rear should be a solid bushing of some sort and the slider I'm going with (http://cmwraceparts.com/Springs/springs32.html) already comes with a solid aluminum bushing, but I've read in recent posts that some people are putting the spherical bushings in the rear spring eye as well. What are the effects of adding another spherical bushing? Just at a glance it would seem like this would allow lateral movement of the rear housing, but as long as the springs are torqued tight to the spring pads, I guess the leaves would only twist tortionally without bind. Would I need a lateral location device? How about a sway bar? Also, for anyone who has rear sliders, would there be enough clearance for the leaf to rotate about the spherical bushing without hitting the slider rails? Thanks.
