    I have a 84 blazer with a 10 bolt rear and a driveshaft out of a 78 with a 12 bolt does anyone know what the combination ujoint number is for this? Also will I need one for the front shaft also or will it be the same ujoint for both years?

  2. I don't know the number, but if you have both U-joints you can take them into NAPA and they will take the measurements and hook you right up with what you need. Good Luck !

    Either Napa 447 (likely with your newer ride) or Napa 348.

    Your front should be the same as you're running now.
