Some other pertinent specs:
Seat tube is 29.6mm outer diameter. They came OEM with a proprietary Huret FD clamp and proprietary steel seat collar with 29.6mm ID. I had good luck sanding out a Suntour 28.6 FD clamp to fit on the seat tube, but not with replacing the seat collar. A 30.0 Phil seat collar was too loose. The chromed steel one it comes with works fine though. The seatpost size is 26.8mm- luckily lots of those around because this was a standard size for lightweights in Japan and France for many decades.
Head tube/steerer/headset is "OPC" or old school BMX sized. Meaning steerer ID is 21.1mm and the headset cups need to be 32.6mm OD. Even though the ID of the steerer is odd, the OD is the standard 25.4mm, which means a regular ISO headset locknut and 26.4 crown race will work fine.
What else...the fender eyelets are usually unthreaded from the factory. On the Sports Tourer the dropouts are Huret with integrated hanger, so you'll need an adapter stop washer to use a non-Huret RD. On the Super Sport, the dropouts are stamped with no hanger, so any claw RD will work.
