Performance gearbox tailhousing mount for 69-94 1750 and 2000 Alfa Romeos.  Replaces the flimsy rubber bushing that supports the tail of the engine/trans mounting triangle. Remove a major source of parasitic horsepower loss due to misalignment of engine and driveshaft. The stock (a rubber thong) bushing does little to support, much less secure the tail of the gearbox as it slams around shifting gears and winding up under acceleration loads. Works for race or street machines to firmly fix the location and retain minimal flexibility. Why spend money to create power up front and have it unnecessarily diminished before it reaches the rear wheels?
