Want clean plastic storage storage boxes to store and ship Mopar 8 3/4 chunks most say 9 inch ford. Jegs, summit, spreedway

I am afraid that one is also for the Ford 9", and if you look at my photos, you will see the 8-3/4 comes close to falling through the hole in the 9" round case. I find the rectangle box is also much easier to hold and carry.
