Default Differential drain plug

A while back, someone posted measurements and instructions on how to drill and tap to bottom of a differential to drain the fluid. I can't find this post. Does anyone remember the info?

Regards, Dave

There website says:

"This procedure does not affect the integrity of the differential in any way."

How do they KNOW that for sure? I'm not saying it does, just wondering if they could PROVE that claim.
