Took the opportunity to have remaining niggles dealt with!
When anti tramp bar removed to do bushes, we noticed the mountings on the diff cover weren't great so they've been remade and all is much better at the rear. Also dealt with annoying slight resonance when moving away which turned out to be the gearbox mounting - replacement was a Chrysler Valiant one!
Traced annoying fuel smell at front to incorrectly seated air cleaner and that's now sorted and took the time to double check chassis etc to ensure no incipient corrosion anywhere.
Not content with that, reset the tappets which hadn't been done since heads done a year or so ago and as we were on a roll decided to see what was going on inside the rear suspension units!
Bearings not great on one side and and even less great on the other so they were replaced. After reading extensively on here and SLJ's technical notes and suggestions decided to fill with semi liquid grease and added a grease nipple and a vent so one can fill them without pressure build up.
Needless to say car drives and rides incredibly well now and am looking forward to the serious touring mentioned below!
