i have a 31 chassis we are building into a great race car. we want to retain the rear mechanical brakes but want to go to open drive. does anyone know of either a conversion kit to make the closed drive prinion to open drive with a yoke, or does anyone know of a later chevy center section such as 55 and up that will go into the 31 housing and if so are the axles from a 31 go into a later center section
