NOTE: To determine if your Series 2A is fitted with either a 9" or 9.5" Clutch, inspect the slave cylinder, if there is a 1/4" packing piece between the slave cylinder flange and the mounting bracket, then you have a 9.5" clutch, if the slave cylinder is bolted directly to the mounting bracket, then you have a 9"clutch. All Series 3's were fitted with a 9.5" clutch.
