Ring gear size

Ok this is an easy one for all the chevy persons...... 98 silverado,ext cab, 5.7 vortec, long bed. rpo code GT4.... which i believe is the 3:73 ratio... so my easy question is what size is the gear? 8.50 or 9.50... the cover is 14 bolts, and cover bump is on the drivers side. need to get these seals so i can replace them
