Good question. I stumbled across a Moulton, at the local landfill site (dump) many years ago...
I had little interest in the bike and I swapped it for a Brooks Pro saddle which was fitted to my first Marinoni...
As for the rear fork pivot, not sure. Vintage bike restoration should be considered with care. As often as not, destroying the original paint, art and patina can be a mistake, a costly one I might add. Be sure that painting is the best way to go. It might be a good idea to show a picture of your bike before proceeding. Just a thought.
As for the rear fork, in my picture it looks like a grind job might be the way to go, Again, close up pictures would prove helpful.
