Power station rack mount screws

So i got the deluxe rack mount kit, got the ps2 mounted. The tolexed fryette rack case just came in from motor city guitars but not screws or anything to mount the actual rack kit to the rack case. Was i supposed to buy this hardware seperate?

Hang on, lemme guess. I remove the feet from the PS and use those screws to mount the rack to the rack case? Cause that worked for me…
