What are we doing wrong?

Hey guys, my stepfather and I are replacing the 7 1/4 rear in his 72 dart with an 8 3/4,(3.23 gears, 489 case) open gear rearend. We are at the stage where we are installing the axles and backing plates. My stepfather bought Yukon axles from Mancini Racing to be installed. We installed the passenger side with no difficulty but we are having some trouble with the driver side. The axle will not sit all the way in to the housing when pushed into the tube. Everything looks like it should, but we cant get it to go all of the way in. The axle sticks out about 1 1/2 -2inches and refuses to be pushed in any further.

The axles are the same length, aren't they? Were these axles designed to only work with some sort of suregrip? Any ideas on what's going on?

thanks for all of your help guys.
