It is highly likely that they will be either 8-32 or 10-32. Take one of the others out and measure. 8's are ~.16" and 10's are ~.19" 10-24's are quite uncommon in aviation, but if they are 10's it would be wise to compare the threads to one of the 8-32 screws in your bin to be sure.
That divider is aluminum, if I recall, so if the screw threads are messed up that bad, you need to carefully check the threads in the divider for damage and make sure there is enough thread meat left to hold on.
