Thanks Dave W, these pics show me what I am dealing with. John V6, I may call on you for some pics. I think it's going to be replacing one or both UJs. I think the car has got very wet underneath as I discovered rust inside the rear brake drums, and a seized piston on each side's slave cylinder. I'm coming to the conclusion the UJ(s) have been waterlogged, gone rusty (due to the car standing for long periods (only 300 miles in the last year)) and have broken down causing the clunking sound. The car is going up on a friend's ramp on Saturday so we can have a good look. And work out how to remove the prop shaft if we need to.
