So I've seen a couple horror stories about ebay items and makin' things work.. Got a full set of Confer 1.5" shackles with 5/8" bolts.
Going on 76' FJ40

You want the 1" OD bushings. Those will fit your stock spring eyes.

Good luck!

From what I understand, the problems people were having with the conferr shackles was that they wouldn't fit over the flange on the bushings.

You need bushings with a narrow shoulder for the shackle mounts on the frame.
