rear tub mounting points

hi all can someone tell me where all the rear tub mounting points are for a defender 90 please and will i need to remove the seat belt anchors behind the front seat
cheers toby

For some reason I cant load my project write up in pdf, but I have extracted the text and included it below. I was lifting the complete body from the chassis. Hope it helps.

Started at the back, removed the ten bolts holding on the rear cross member.
Disconnected the wiring to the rear lights by removing the panels behind each cluster and disconnecting, taking note of what goes where.
If I was doing this again I would cut the loom under the tub after it comes out of the chassis and fit a decent connection box , something like a “Rubberite” one. This would also provide a good interface for the tow bar socket.
Moving forward, there are two brackets coming off the middle cross member to the tub. The one on the driver side ended up a disaster for me. The tank left very poor access, and the bolt head was spinning in spanners. Couldn’t get a socket on it. Ended up spending a couple of hours with an air chisel.
Next up, remove two bolts on each of the rear out riggers. No bother with these.
One big bolt on each of the front outriggers. I had to drive them out with a punch. I guess these could be fun putting back in.
Remove the two bolts that go through the chassis legs, from the bulkhead brackets, just forward of the front outriggers.
Remove the bumper two bolts each side .
Remove the front grill, and the panel behind it.
There is a bolt underneath to the chassis on each side.
And a couple each side into the front wings
Into the cab now and remove the seat bases and floor plates, remove the battery and push the battery cables down out of the compartment. Remove the main gear leaver and the tunnel cover.
There are two bolts from the floor pan to the chassis, one each side of the gearbox, just in front of the seat box.
Into the engine bay now and disconnected heater hoses from the heater. I removed the air cleaner and piping. Disconnected the wiring harness under the brake servo. Disconnected the heater plug feed from the first plug. Disconnected the trottle cable. Disconnected brake pipes at callipers and some on the bulkhead. Unbolted the diesel filter housing, complete with pipes, from the bulkhead. Unbolt the header tank and power steering reservoir from the inner wings and leave dangling. (probably missed some stuff here, but you get the idea).Disconnected the clutch hydraulic pipe.
For the steering shaft, I loosened and removed the pinch bolts on the upper and lower u/js. The shaft can then be pushed further up into the top u/j until the bottom one clears the steering box shaft and can then be removed
Removed the fuel filler neck from the body, this required more air chiselling as the nuts were unmoveable and inaccessible.
For lifting the body, I erected scaffolding and two chain hoists. At the rear I used scaffold bar under the chassis in th rear wheel arches.a lifting strap at either end. At the front I used a chain connected to the bulkhead chassis brackets.
The body lifted freely from the chassis, the tub needed a slight lever.
I lifted the body about a foot and then wheeled the rolling chassis forward out of the body.

PS: 1989 pickup
