The desirable N-style, nodular-iron gear cases are available in four different versions. There are three versions with external Ns cast in; note the more curved style on the top right. The unit on the top left seems to be nodular iron but requires a little more investigation to verify.

This is when making a few phone calls to reputable axle builders can be helpful. There are quite a few companies making Ford 9-inch housings to fit just about any muscle car out there, including non-Ford vehicles. (See Chapter 8 for how to install a 9-inch in a classic 1957 Chevy Bel Air as a performance upgrade.)

The aftermarket Daytona-style pinion cartridge accommodates the larger and stronger pinion head bearing. This particular pinion cartridge is well reinforced and much stronger than the stock production cartridge.

Here are the internal sides of the same three units. Now you can see the C4AW-4025-B part number on the lower left unit, which verifies it as a nodular unit.

The axle housings themselves had many different variations over time as well. These variations include different-size drum brakes, disc brakes, and wheel hub arrangements.

Since these housings were a series of stamped-steel pieces all welded together, there were many different overall lengths, tubes sections, mounting brackets, and even general constructions over the years (see Chapter 5).
