I thought I should mention my newly discovered trick to remove rust! The photo above shows the brackets that mount to the side of the chassis to hold the running boards up. The brackets on the left are 'as removed' from the chassis. the ones on the right have gone the process of 'electrolysis' with a battery charger in a tank of water with 'lectric soda' mixed with it. I was very impressed with the state of the metal as it came out of the bath. If your going to try and do this at home, do a search on the internet for the instructions. If you get the polarity wrong on your part it can actually eat it away!
