I still have the first car I ever owned, a 1931 Ford Victoria, purchased in 1957 for $140. The car has had several different combinations of engines, transmissions, and rear ends over the years. I last rebuilt it in 1978, using a 350 Chevy, linked to a cast iron T-10 4-speed, from a mid 60's Buick. The rear end is from a 51 Olds convertible, with a 3.64:1 gear ratio. The front disk brakes are from mid sized 73-77 GM, a great improvement over the previous 47 Mercury units, and the rear brakes are still the Olds units.
