I think i got it, so the 1 washer goes on the top, sitting in the oval?

We only use 1 washer with these, unlike the stock pistons come
with a washer on top and on bottom.?
Only washer on the top because the bottom piece is machined
to sit on the shaft perfectly!!!

NICE JOB MARCUS!!!, so we can use the DRILL set to make holes bigger if we want to....
I was going to use the drill set on the STOCK blank AE pistons...
