Clutch release Bearing Adapter for 750/101 & 105 Cars. This adapter is designed to allow the use of a 1750/2000 engine and clutch in a 750, 101 and 105 models with a mechanical clutch. The car retains the original cable-actuated clutch linkage, but can use the 1750/2000 release bearing and the larger, stronger diaphragm clutch. This requires machining a 1750/2000 flywheel to accept a 1300/1600 starter ring-gear and bell-housing. Requires an OEM release bearing, sold separately CL009/1.
