Success!!!
Came off really easy with my wife's help
I used two engine cranes, the first one is bolted via a piece of angle iron across the rear mounting points for the front seats. I used a leveling cradle to spread the load and more importantly give some control over tilt. I backed this up with a ratchet strap which hooks under the sills but having felt the lack of weight in the body I would say this isn't necessary -
For the back I just used a circular strop around the rear cross member -
This way I could lift the front and back a little at a time.
Just a point for anyone doing this I see a lot of people mentioning 10 fixing points between the chassis and body. There are actually 12 - 2 at the front holding wings in position, 2 at the Bulkhead, 4 in total holding sills in place, 2 at the rear cross member and the 2 I missed which are on the inner face of the chassis directly underneath the rear seat cross member.
So after I found these two fixings the body could be raised off the chassis a few inches and I checked to make sure it was free.
Now the next part of my plan, using wheel skates I removed the front wheels and lowered down using two trolley jacks a little at a time each side -
Then repeated for the rear axle -
Doing this you gain quite a bit of clearance and saves raising the body too far -
It gets quite windy here and it was a little disconcerting watching the body swaying, but wifey held it steady -
In addition wife and I where then able to pull the chassis forward a few inches to clear the engine from the rear of the bulkhead then out to the side, skates worked a treat -
Then lower the body down onto some axle stands, the wooden blocks have a slot in them to locate the blade of the sill -
For safety I will leave the jacks in place but there is no load on them.
Then wheels back on the chassis. Next up is to give everything a good clean, empty fluids and remove the engine and gearbox/transfer box. Still not seeing anything to worry me on the chassis, looks solid -
Really chuffed to get this done I have thought about it for what feels like months
