I checked the Maxperformance online parts catalog and for some reason couldn't find a part number for the rod assembly, but it is in Group 0.854 which may help your search.
The Z-bar (countershaft) is in Group 0.852.
Part number for 1965-1966 P-8 cars is 9779221
Part number for 1967-1970 P-8 cars is 9787237
