The only thing I've ever done to make them better (all I know) is obviously the shortest flange, to flange width you can work with helps keep it from bending the tubes forward, and putting a Mark Williams cap, or something like it on the left side carrier bearing since that's the one that wants out under load.

I did see one, that was a PS rear, that had a load bolt built into it.


The funny thing is my MW center sections all have 3.812 housing bores like a 60. All my mope setup measurement stuff works in them lol.
