Not all ribbed center sections are nodular. The early WAR casings were double ribbed but were not nodular and are the weakest of all casings. They are called WAR casings because the paert number starts with WAR. Stay away from those. They are weaker than the regular one ribb grey iron cases.

The Nodular cases were double ribbed and some (not all) will have an N in the center over the pinion. You have to do some research on the web and get the part numbers so you"ll know if one that you are interested in is nodular or not. Some had the N in the center but the caps did not meaning that it had non nodular caps. Try to find one that you know is nodular and the caps also have the small n on them.

You might look into an aftermarket case on ebay cause the factory N casess are sometimes priced higher than an aftermarket case. George
