8-3/4 Wheel/Axle bearing question

I checked out a few places for prices and got mine from National Moparts up here in Canada. Their # is 705 426 2993, not sure of the part #. What year of rearend? FYI, I tried changing my own bearings and after swingin and swearin for about 2 hours, I took them up to Nat Mop to do it. A press makes things soooo much easier.

**I checked my 69 parts manual and part #'s for bearing and cup pkg is #2525415
