In my experience I think the insert rod bearings used in the C69A engine were thicker than the 8BA insert bearings and the inside diameter of the C69A rod was greater. C69A insert shells and 8BA insert shells were not inter changeable.Repco made replacement C69A shells but hard to find now.Best way is to use 8BA rods and bearings. Someone else might shed some light on this. Cheers
