Not at all, the factory bolts holes are offest so the passenger side bolts further forward. The NNBS seats all bolt together in line if that makes sense. I had to stretch the frame on the jump seat to go wider than the tranny tunnel.
I will say though it was totally worth it, they are a million times better than my old seats. The best part though is the jump seat has a lot more storage than the old center console and a 12v outlet in the bottom, and then it's even lockable.
