8-3/4 axle seals?

Thanks guys! I'll see what I can get figured out tomorrow. Returned the seals and they didnt have the right ones in stock. So I get to go back tomorrow and get them! Jeez..
So anyway, if I can't adjust the play out of the axle with the adjuster, do I need to look at new bearings or the center chunk? It's a 741 open differential with 3.23 gears.
