OK, a mixture of satisfaction, amazement and disappointment today.
Satisfaction in that I stripped, cleaned, de-rusted and painted the axle, trailing arms and ARB
I also took the diff cover off, drained old oil and inspected the crownwheel and pinion which looks in fine fettle. Won't know for sure until it's on the road tho. New gasket and Wellseal sees it back together.
Amazement in that I started stripping all the crap from under the O/S rear wheelarch to reveal nice original paint and original inner arches needing no welding. Just a good wire brushing and some Kurust and it'll be fine. I am astonished to find the leading and trailing edges totally original. A first for me in Dolomite ownership. Pics are poor as from mobile phone.
Looking rearward
Looking forward
Disappointment in that further investigation has revealed the boot floor section is rather thin where water has sat in the recesses. It will be easier to put a new boot floor panel in. The inner arches and bit of boot floor which is actually part of the rear panel are fine and rust free.
If anyone has a boot floor panel either new or removed from a car, I'd be interested.
