We found both of these on Craigslist. They have a pretty good search facility that lets you narrow your search and scan all the Craigslist ads across the country.
The 67 had a set of extended forks and the wrong gauges and headlight. From there back it was relatively stock except for the exhaust. Stripped it down to the frame, had that powder coated and the tank and side covers repainted as per original. Should come out pretty nice.
