Any V8 bellhousing 55-66 will bolt in for you. Use the flywheel correct for the engine. Clutch will likely have to be looked up by dimensions. You will probably have 1 1/8 inch 10 spline input, and either 11" or 10.4" surface. GM used both for many years, just know what you need when shopping. That should hook you up to your original tranny as well as later model open drives. That same bellhousing and clutch setup will also cover passenger car transmissions like Muncies and T10s if you're so inclined.
