Suspending the engine/trans assembly without some support at the bell housing will break the bell housing. You'll need a 1961 V8 bell housing with the hydraulic clutch setup, with the throwout fork and slave cylinder on the passenger's side. Then it will be a bolt-in swap. Saginaw 4 speeds have a cast iron case- - - -no rear mount should be needed, but a universal tubular mount the hotrod shops sell would be an option. DO NOT do the front/rear mount setup without supporting the bell housing.
