71/72 Dana 60, why two drum sizes

Post by general » Wed Apr 04, 2007 3:56 pm

Was talking last night with a fellow member and this topic came up. He asked what size drums I had and I said 11". Looked today at Galen's white book under axles and for 71/72 they list two different axles with 3.54 gears( look at arrows on the attached) one with 10" and the other with 11" drums. How or what had to be ordered to get one versus the other. They are both listed under the A33 package but have a different code on the build sheet, 050 vs 051.

Can someone explain.

Opps the lower arrow is in the wrong place just move up by one
