An update on this. Sorry, I haven't been around much just lately.
I ended up paying a local mechanic £50 to change the rear shocks for me as a recent operation on my leg meant getting down on my hands and knees to do the job was going to be painful. I did try to see if I could book into one of these self service garages (the one local to me is called "This is your garage" which is based at Culham in Oxfordshire. I've no connection with them btw). But due to Covid-19 restrictions they cannot allow anyone to rent ramp space at the moment. He did mention that there were a couple of mechanics who use the place as their working base and put me onto one of them.
Anyway, long story short, the mechanic used the same bolts. I did mention about replacing them to him, and that there was a suggestion of tightening them to 150 Nm, and then through a further 65 degrees. He said it wasn't necessary unless the bolts had damaged threads, or damage to the head of the bolts in getting them out. He's done loads on different cars in his career history and not had to replace any yet.
