what a absolute pig..........
Got it!
I am sure lots of people can remove and fit the leafs but my first time so happy to pass on my experience.
I found the trick to fitting the leaf is to...
Use nylon bushes on front shackle and rear. You will need to use the rare spares saddles as the nylon one is too wide. Also you can not buy FE leaf springs from King Springs any more so you need to get them reconditioned. Use nylon leaf plates in the leaf. You need to cut down the nylon bushes so they fit along with the front shackle pin tube supplied with the nylon bush. Use existing bushes or length of pins for correct cutting measurements.
First clean everything especially the fittings. Put the front shackle nylon bush in and get that bugger in to the body mounting. Took a couple of goes. Use rubber grease along the sides as it helps. Then fit the shackle pin tube in from the open side. I had to lift the leaf with one hand while moving the pin in. Next align the bush and check it does not fold on the sides. Get the pin and apply plenty of rubber grease. The idea is that only the pin and inner tube have grease. Had to turn the pin so the thread would go through and again lift the leaf with one hand while aligning the pin head in so there is enough thread on the other end to get the bolt on. Then holding the leaf so it is kept aligned tighten the bolt so the pin head goes all the way in.
Second put the rear pins in. Had to lift the centre of the leaf with a jack and put a piece of wood between the leaf and under body so the rear pins line up and fitting is easy.
Hope this helps someone.
