First I don't much about the different rear axles, 12 bolt, 14 bolt,etc.
I was told by someone at a swap meet last weekend that they had put an Eaton pumpkin in a 14 bolt rear axle. The only problem they had was to swap the axles because of the splines. If the reverse could be done, 14 bolt pumpkin in an Eaton rear axle, that would make more rear axle ratios available for the Eaton.

You can put a locker from a 14 bolt into an Eaton but you have to use the 14 bolt axle shafts and spiders. You have to stick with the Eaton ring and pinion and carrier though. Other than that nothing else is compatible. The Eaton has the drop out style center section like a Ford 9", the 14 bolt does not. (Salisbury type)
