Wagon specifications

Been doing my best lately to search the forum and learn as much as I can about the fuselage wagons. I'm curious if anyone has compiled a list of standard specifications and/or options that could have been ordered?

For instance, I've been under the assumption that all C body wagons have 8.75 rear ends, but then I questioned if maybe they used a lessor duty example for wagons optioned with a smallblock.
