Good used right (long) side full floater axle shaft for 73 - 87 GM / Chevy / AAM Corporate 14 bolt rear axle with inboard mounted break drums.
Length is 37-3/4" from axle end to inside of full floater flange.
Please verify your length, Chevy used some variants of these axles!
Good splines as shown.
Getting hard to find these, grab a spare now and insist on OEM quality and fit, not a made in India "Chrome moly" universal replacement.
