there is bolt holes at the bottom of the b piller, and holes in the roof between c and b piller. There should also be holes inthe gear box tunnel. The ones in the floor, you will need to put a backing plate underneath to provide some beef for the mounts.
easy as!
The back is very different as there are no mounts anywhere. I am in the procss of putting mounts on the back of mine. 4 in the floor, 2 in the c pillers and 2 under the parcel shelf.
