anybody ever put a drain plug in their 8.75 housing

My driveline shop did one up for me. I believe they drilled a larger hole then welded a bung underneath with a plug. But to protect the plug from damage when you jack the car up, they also welded a short piece of thick pipe around it for the jack saddle to contact.

I also had them weld a filler cap at the top of the smooth face for filling and gear inspection. (Car doesn't have the OEM gas tank to get in the way.)
