SB: the OE ones have a pronounced L/R offset but I have some replacement SB ones from the dealer & the pushrod round recesses look "almost" centered (I was expecting the offset) & no numbers just a "X" on the horizontle oil deflector tab on the top side above the pushrod oil hole. Pedestal slot is a weak 7/8" long/strong 5/8" wide.
