So, the galvanised rear beam axle was fitted yesterday along with new OEM Spica dampers, new springs, new brake discs, calipers and pads and wheel bearings. All the tie rods have had new OEM rubber bushes and a further coat of fresh underseal has been liberally applied before the beam axle was replaced.

Everything renewed or overhauled. Note fresh underseal.
That's the good news. The not so good news is that the engine and gearbox unit has had to be dropped again due to the fresh oil leak discovered at the hub flange. Luckily, John at Justsuds has found one of these in his stock.
One thing to note is that these seals are different sizes depending on which side of the diff' they fit. The one I need is for the driver's side which differs from the one for the other side by 1mm outside diameter.

Another issue is that the white plastic gear cog on the end of the speedometer drive was found to have cracked so a new unit is needed. These are proving to be tricky to get hold of so could cause the job to be held up. Unless someone here has a spare one they could let me have?

So that's the story so far. To be continued...
