I have a 1972 Ironhead motor that I am dropping into a 1954 K model Frame. My question is, that I have the title for the bike that the motor came out of, but giving that the right case will need to be replaced, which I believe is where the serial numbers are, what would be the necessary course of action, if any, would I need to take?

Louisiana?

Thanks,
Whiskey
