Sell gearbox ST75 buy new. Only drove on the bench for the engine map. Due to the abandonment of the project, the box is sold complete with display, lever, box output tulip, support, right bearing and complete universal joint for wide tracks with 27 spline wheel bowl for C2R2 hub or 25 spline bowl for 205 type hub or sax challenge. The 2 gimbals are identical and interchangeable. Just redo 2 rungs to adapt it to any 106/sax.
