I hate dealerships, usually some jackass that doesn't know anything about Nissans working in the parts dept....unless its Scott from Fontana. The arms should all be the same...it's the front diff you have to worry about if you are going to do a diff swap.
When I did my M226 swap, I was looking for the locker wiring harness, so I went to a dealer thinking they could help. WRONG. Took me 30 minutes of arguing with the parts clown and parts manager, that Frontiers came with factory electronic lockers in the Nismo/Pro-4x package, which is where I got my axle from. "Well, your new axle must have come from a Titan if you have a locker, but parts aren't interchangeable from Titans to Frontiers, one's a full size ones a mid size truck...."
I'm yet to walk into a dealership and find someone knowledgeable of anything other than ripping people off.
