Part number for 8.25 29 spline yoke

Does anyone know the part number for a 8.25 29 spline rear yoke? Or any information? I snapped a bolt off in it, then tried to extract it but just effed the whole thing up. Ugh.

I believe all 8.25 yokes are the same....the spline count should be the same on them its the axles that have the different spline counts.
Ive never seen a 8.25 gear set that referred to a 27 or 29 spline pinion choice.

They all have the same spline count (the pinion yoke that is) but there are two lengths... 2.75" and 3". I forget which one goes with which axles but the switchover is somewhere in the 94/95/96 range.
