Standard AP oil pump for A+ 1275s, but will work with pre-A+ non "S" large bores provided you use a slot drive cam. Whenever you have access to the oil pump in an A series it is a smart idea to replace it to avoid failure. Make sure to pack the pump full of engine lube. 
 
Does not fit automatics. Pre-A+ "S" models will require the drilling and tapping of one bolt hole.
