Evapo-Rust wrap also works! The Gran Sport is an amazing and underrated frame that lends itself to so many builds! The Nervar Star uses a standard 22.0 mm crank extractor and has become one of my favorite cranks. About the only stock part of a Gran Sport I wouldn’t feel comfortable riding with are the stock Simplex bits - but that’s what SunTours are for!

i just completed the Clunker Challenge on a much rougher specimen that now awaits decisions about what form to build it up into next!
