BF plugs are the same as FG's so the BA's should also be the same.
I'm using a full electric BF memory drivers seat frame in my FG and swapped FG cushions onto these frames. The bottom seat is just a bolt on but in order to use the BF electric rear tilt I had to weld the side frame bolsters from my FG rear frame onto the BF's as it uses different shaped side bolster frames.

I've now swapped all this into FG XR seats
