hey does anybody happen to know the dimensions of the Recaros that come in 8s and 9s?? like the width of the base in the front of the seat and in the back of the seat . then the widest point of the top and the narrowest part of the top. then the length of the base from front to back and the height of the seatback from bottom to top as well as the measurements of where the sliders connect to the bottom??

any help would be greatly appreciated
