Rear axle housing swap

I have a e-locker that has a very rusted housing. I have access to a very clean non-locker housing.
I thought the housing is identical except for an area that is machined to clear the locking mechanism.
Is this true and if so, does someone have specifications of what requires machining ?

 

Can anyone confirm that an e-locker case is different?
Thanks

 

Yes the e-locker case is different, but a non locker housing can be modified. It needs grinding in 4 locations and 4 studs installed in new locations. They used the gasket as a template. Dig around a bit, there was a write up on one of the other forums and there are probably YouTube videos.

 

Thanks, I was hoping to prepare everything to do a quick weekend swap out .
