What, if any, are the differences in the 14 bolt FF between these to types of trucks? Do they look different? Is one axle wider then the other? Are the axle tubes different diameter? Here is why I ask. I am about to order the spring plate anchors from the dealership so I can do my axle swap. I want to make sure I get the right part since they have to order it in. The u-bolts are no biggy since I can take them home and see right away if they will work. Any help would be appreciated.
