Hi David,
Thanks for the advice. I ended up taking the door of the hinges to move it around enough to get to the bolts. After trying for an hour to get a spanner onto the bolts without rounding the heads taking the door off seemed the simplest option. Bit of job managing the door when it was off both sets of hinges but I got there. Driver side all bushes were totalled, passenger side there was some life left but all got replaced.
What a fiddly job, took me 5 hours in all start to finish with the usual healthy portion of swearing and cursing.
Nice finish though - that solid clunk as the door closes is satisfying.
Nick
