Scr33n uses metal L brackets , so IMHO its totally not nessesary to apply these bolts seen from a constructive view.
if they are original there, it could be a consideration, but thats up to Screen how genuine he wants to make this replica.
it looks that the original have them there , and also in the sidepanels, so i would say if you leave them out on the sidepanels , i would not put them on the front side
