There are others that will work [65-67 Chevelle, 68-74 Nova, 70 Camaro].
If you are intending to start with a 12 bolt axle they are expensive to acquire, expensive to restore/rebuild and will still have the built-in design limitations, namely drum brakes and C-clip axle retention. Cutting/welding on the axle tubes can warp and weaken them. Many 12 bolt axles were in cars that were abused; I've seen cracked center sections and bent housings.
By the time you are done buying, rebuilding and modifying you will have spent close to the cost of a new custom-built 9" or 12 bolt with discs, better axle retention and the ratio of your choice.
Were I building a hot rod that is what I would do.
