altec lansing 802 8g HELP!!

Greetings . This is the 1st thread I have posted.
Pardon my poor english.
My question is regarding a pair of 802 8g that I have acquired over ebay. They came without neither diaphraghm nor the bolts for mounting the diaphraghm. I understand that diaphraghms can be bought from great plains audio. However I need directions for the bolts. Bolt size measurements should suffice as we have a shop that specializes in selling nuts and bolts over here.
Thank you in advance .
