Parking Brake Compatability

Does anyone know what the designations for parking brake assemblies is (i.e Part # 220420 03 12 SIMI (in OVAL) 5.6? Have seen 4.3, 6.3, 5.1, 4.1 etc.Bolts mounting distances seem to be equal, think the pedal lever length is the difference, ANYONE? Have a 2000 CLK 430, need new parking brake assembly...
