Antoher Rearend I.D. Question....Please !!!

[rod locker]

On a 74 Duster with a 904 Trans.........My rear end had a small tag with 2.71 stamped in it identifying the gear ratio. My question is my rear end cover is a 10 bolt, with no drain plug except for on the very top of the rear end just before the housing. I looked at the rear end I.D. guide listed in the the tech section but it does not show mine. Anyone got any clues what size this could be?

Are ya sure it's not an 8 1/4" they're 10 bolt covers.http://www.moparts.org/Tech/Archive/axle/6.html

That's my guess 8.25....seems to be the exact one I have beside the garage and mine is supposedly a 73
