I changed my seatbacks for personal reasons.
Instead of the 7/8th inch cut I made mine 2".
You can fold the seat till it hits the stick and it
will also help in loading your WIFE'S bags
I hope this can help someone and I know I am
not alone.
Also, have you checked the seatbacks with the vertical flap compartment brace in place. The brackets for that brace (that attach to the seatfloor over the center tunnel) prevent my seatback from going full forward anyway.
