I have a 37 GMC, with a 250 from a 72 nova and a t5 from I don't know what mating these 2 things together is a bell housing from a 70 something Chevelle. Now for my question about flywheels are all the small block and newer 6 cylinders flywheels the same or what. I know about the differance in teeth and clutch size. I just need to know what flywheel to get

Thanks
