The rest of the refit went fairly easily, but got more and more cramped as the bits went in.
The power steering pipes were particularly troublesome as I replaced with new instead of using 30+ year old soft stuff for the low pressure side, the oil resistant stuff in the correct size was so resistant to going around corners I had to use some 90deg elbows instead of trying to turn tightly.
I'd found a new middle & rear exhaust online so with the front pipe in decent enough shape I used them, I have had a few cars that I've had stainless systems made up for which I may well do in the future, nothing too moisy though mainly just for length of life!
