Swapping diffs on a 7 1/4

Check the backlash and gear patter before you start, I would try to keep the adjusters at the same number of threads and set the backlash the same to start. I have played with these little rears some. Not hard to change the parts but the trick is keeping them quiet. Ring and pinion need to end up close to original relationship or you will have gear noise. Factory service manual would be good to have .
