Some of the info that keeps getting reposted as gospel is just not so in my own findings.

There are reasons to run either rear. Most are buried in the misinformation posted on here. I have ran a Dana 60 for 20 years. Never bent the housing and it has no brace. I use a lw cover with no links to a brace. When the tubes are welded to the center housing it makes a very strong unit.

The reason to not run a Dana 60 is gear choice when needing a pro gear. You are limited with 4.10 and whatever lower gear may be on a shelf somewhere.

9" is plentiful with any gear imaginable. A lower pinion with more mesh. You may or may not want this.

A heavy leaf spring car never seeing over 1000 LD ft of torquefrom the crank will do awesome with a Dana.
