there are numbers and codes on the axle tubes that will give you the correct stuff. I have a 70 GMC K20 and we have discovered that the front axle on that is a one-year only GMC only thing. It has drum brakes.

Look in the pickup thread to see how other folks are showing pics of the numbers on the axle tubes. I think they are on the LEFT (driver's) side of the differential and may be where the U-Bolts are. You'll need a wire brush and maybe some sandpaper to find them.
