Hello all, I have never posted here before, but have been reading all the great info. you all are continually putting out there for quite some time... Thanks again!!! I recently picked up a pair of 802-D drivers w/o diaphragms, and the three screws which hold the diaphragms in place on each are also missing. I believe they are the same screws the covers use as well. I have a pair of 802-16G's with diaphragms I'd like to swap into them but I cannot for the world find any information as to the exact screw size to find replacements. I understand these must also be non-magnetic composition. Any help would be greatly appreciated. Thanks so much if anyone can be of assistance.
