The front seats fit onto the original runners, easy.
The back seat squab is the same shape, but the rear backrest is one piece on the Samba rather than the two piece split fold.
I ended up removing the rear covers and then re-covering the LN backrests with the Samba material (the back is screwed on and made of steel) so I glued on the new material and secured with the steel cover over the top.



I'm going to have a go at fitting slide / tilt runners to the front seats as they just lift at the moment and as these seats have headrests they hit the roof.
You can get in the back if you slide the seat fully forwards first.
Saying that, only the dog will ever be going in the back, I don't think I could get in there!
