Size and pitch of water pump bolt?

Just need to know what size and pitch the threads are on the waterpump bolt for a 99 F-Body. Thanks

Since nobody has replied i'll throw out a guess...If I remember right the rocker stud I bought is the same size, it was 8mm x 1.25 pitch, I cant find the receipt but i think thats what it was.

This is the way GM lists the bolt:

BOLT, W/PUMP (USED W/SEALANT) (M8X1.25X82.6, 31.8 THD, 17 OD, 10.9 GM7114MMZF)

Part # 12551926
