Someone has already said it, pull the painted bits and sell them to the collector and then put a new set on the bike and sell that. I know, it is not the same, but if you were a collector you would not ride that bike anyway as you may be forced to test your helmet (or DOT approved bandana in Texas) and then how much would that stuff be worth?
As far as the pipes go, I have the same one on my '70 CB750 and I will either leave them the way they are (they do sound nice) or chop them off at the pegs (rearsets).
I may make him an offer on those bars and install them upside down, Clubmans, eat your heart out.
