I didn't compare cranks today, but I did measure some spigots and surprisingly I found the opposite of what I was expecting. The spigots on the /5 jugs were a few mm longer than several nikasil cylinders which I measured. Now that you have that information logic will lead you to conclude what I found which is that with a 1970 r75/5 block and crank I have no clearance issues with the length of spigots on a pair of 800cc nikasil cylinders.
