Interior swap
 

I recently traded out the cloth/ neoprene interior of my 2010 to the red-black leather interior. Unless there was something unique about these seats, it is NOT a direct swap.

The back seats and the driver's seat are all painless. The front passenger seat's shoulder harness mount seams to be different. The rail that the shoulde harness attaches to in order to make the lap belt portion of the restraint connects to a bracket attached to. The seat rail itself, not the floor as on the driver side ( and probably series 1 passenger side as well). The holes required to mount the bracket are not present on the older seat rails.

So, you have to swap the entire seat rail system out on that side. This is fairly simple...about like moving a desert with a spoon. It doesn't take a lot a brains, but it does take much longer than just trading out the seats.

I guess this is more of an FYI for a DIY than an actual DIY.
