Quick update.
We have finished the interior strip down..really smelly!
I will be changing the srs module and probably the fuse board but luckily I haven't found corrosion on any of the connections yet.
I think we found why the clutch pedal went to the floor...the slave cylinder is toast and I have ordered a new seal kit for that.
I'm going to get the starter motor and alternator off for testing and or refurbishment/ replacing over the next few days.
The list of jobs is growing by the hour..
