Looks like they are the old CB #1555 two piece rockers. the shafts are one piece with the blocks and separated under the centre spacer. They are forged and look really nice and the rockers actually have a bit more beef to them than their replacments ( #1577 )... But does anyone know why cb changed the design? Anyone have experience with them. how long ago were they "current" as they are no longer avail?
