I contacted a local dealership and asked their opinion about whether or not Titan mirrors would work/fit on the Pathfinder. Showed them that they had the same mounting bracket. To my surprise they told me that their service manager ok'd it for them to try and see if they will fit. They said they would let me know.
Hopefully they weren't giving me BS when they said that, and get back to me sometime soon. I'll keep everyone posted.
