I have a pair of 2470's in need of rear cap screws. It's an 8/32 x 1.5" screw, but the catch is, it has a tiny head (in order to fit into the recess). I tried calling JBL parts, but they no longer carry this oddball screw. I checked McMaster Carr until my eyes were bloodshot, but couldn't find what I was looking for (that doesn't mean it's not there though, their amount of screw stock is overwhelming). I even bought some hex head equivalents, but the head's a bit too big (not sure how successful grinding down the heads would be, doesn't sound like fun). Any suggestions?
