Passenger side axle not going in all the way

I recently had an 8 3/4 clutch type rear end built for my demon. I got it home and put it in and the drivers side axle went in fine but the passenger side wont, it seems like it is hitting something that is stopping it before it comes into contact with the thrust block. Even with the adjuster all the way out it wont clear more then a few threads of the flange bolts. The guy that rebuilt it said i might have turned the drivers side too much when i installed it and gotten it out of alignment. I am using the original bearings not the green bearings (yet). Does this sound plausible and if so is there any way of fixing it without pulling the carrier again?
