The connecting rods come as JJ, II, I, H, etc. The compatibility back and forth can be quite confusing. We talked about such markings and it was suggested that it's a mark simply indicating the forge where it was made. That might be so, but I think that's not the whole picture.
Example - 1981 A3 diagram shows three different connecting rods: ROD-ASSY-CONNECTING | in.Gin. MARK 13251-1051-JJ, CONNECTING ROD ASSY,I | in.Iin. MARK 13251-1006-II, and CONNECTING ROD ASSY,H | in.Hin. MARK 13251-1006-HH.
Example - 1985 ZN shows three different connecting rods: all 13252-1051. Two marked JJ, one marked II. Than, there is the A,B, no mark. So we have 13252A, 13252B, and 13252 and 1051-JJ and 1051-II.
So.. how do you know which is which? What's the meaning of 'in.Gin' or 'in.Iin.'?
Some of them show backward compatible, some don't. How do you match them??
