This works for me.
I look between the tank and seat. I get the pin on the opposite side from me into the large part of the seat hole. Once in, I hold it there while I do the same on the near side of the seat. Once both are in it's easy to slide the seat forward and seat the pins. After you've done it a couple of times it gets relatively easy.
