During this process I had to remove the locking mechanism - which were to say the least looking a bit tatty. Took the chance and gave it a good clean and a layer of paint. It was very red from a previous respray (by PO). Car is green now, and it really looked YUK.

Next week the drive shaft, spring and diff will be removed and replaced by a new parts. Hopefully! I have new AVOs ready, and somewhere in the post is a pair of new longer drive shafts. Some years ago I bought a recon diff from Jon Wolfe. It is a 4.11 but rebuild into a later diff housing (only 4 holes for studs) and with fatter input and output shafts.
