The front propeller shaft has a larger joint at the front end, this calls for a larger diameter coupling flange at the rear of the gearbox. The rear propeller shaft has larger joints at both ends, larger diameter coupling flanges are required behind the centre bearing and at the front of the rear axle pinion bearing. The propeller shaft centre bearing remains unchanged. The sliding joint is now at the middle joint, the rear joint being the high angle type 1358 WA.{Mr Wallis} Details required for car for France.
