Rear End front eye bushings

[Steve68]

I remember reading awhile back, the way to set up the rear end was to go with a ureathane bushing in the rear eye, and a stock rubber type in the front, this would be better for the ride and the suspension wouldn't bind while cornering. I'm I correct with this, or wrong, and body remember? I'm having trouble finding bushings, but have the uerathane,
Thanks for the help, Steve
