Impeller caps...1 or 2? 4.3GL

[Nubby]

I'm replacing the impeller on my 98 4.3L GL. The kit came with 4 gaskets and 2 caps to fill the center hole on the impeller covering the shaft it mounts on. Do I use 1 or 2? Is there supposed to be 2 to give it some space so it doesn't rub right against the housing or just one? Do I even need to put 1 on at all if there isn't much purpose to it?

Also, can anyone confirm that it is supposed to spin counter clockwise?

Thanks,
Nubby
