A little more progress made. The rear tube is now off. I have also removed the seat bases and front floor. The chassis is still looking very good - no rust. There is a dent in the back strut - seen in the photograph. Not sure I will be able to do anything about that - should be OK once painted.
The rear diff looks like it has some oil leaking around the seal - so that will need sorting.
Next job will be to take fuel tanks out.
