Picade Screen Mount kit

Hello,

Today I just got in an arcade kit with screen ordered from Adafruit(US customer). Started the build everything went fine, well that is until the monitor mounting step. The rubber feet that insert into the tension bracket square cutouts were completely missing from the Driver board kit for the LCD, I checked , double checked and went through the entire kit with a fine toothed comb to make 100% sure it didn’t get displaced while building or anything of that nature.

I kind of need a solution as the LCD slides around a fair bit or slowly falls after a short while making it unideal to actually play on, I’m more afraid the LCD ribbon cable as they can be delicate.

TY and I appreciate any help.
