The 5 pieces in the middle of the top photo (with the metal inserts in them) are leaf spring bushings.
The rest of the parts in that photo are body mount bushings. But they don't look like they are any kind of lift block, just the standard replacement bushing. Half goes above the frame tower and the other half goes under it.
There are 11 total body mounts on a YJ, so it looks like you only have a partial kit to redo the body mounts.
'87 YJ, 4.2L built and bored, 8.5" of lift, 8.8 rear, AX15/NP 231, Tom Woods drive shafts, Flat fenders, 12,000LB winch, Custom bumpers, Rattle can paint job. Never completed...
