The 2017's had rails with 2locking bolts in under the front of each seat. They were simple to release and easy access. The rails were long enough for me to move my seats slightly closer toward center with the middle seat removed. this gave me a little more room on the outside of the seats on the port side having additional space for rods to lay was a good move for me.....
I would like to know as well. I have a 2021 z18 and I wanted to tilt the seat forward cause they lean back too far. Also trying to get information on the dowco cruise air seat that has a recliner. Great feature that was offered on the z20 option but not z18.
If anyone out there knows how to remove them that would be a great help. Looks like the bottom cushion has to snap up. But I put a lot of force on it and I don't want to break it..
