The 14bff uses a 1350 u-joint. Your stock k-5 driveshaft will use a 1310 u-joint. A conversion u-joint has two 1310 caps and two 1350 caps. So by installing a conversion u-joint you can re-use your k-5 driveshaft and it will hook up to the 14bff's yokehey pauly 383 what do u mean a conversion u-joint??
