All the seals I've purchased over the years, regardless of seal design, come with the little plastic piece to aid in the assembly of the seal. This plastic tab helps prevent the backside of the seal from getting chewed up as you rotate the seal into the block. You can find install videos online if needed.

Right, I thought it was strange this kit didnt come with one, the other one I neglected to post has it.
