The OE rubber bushings are preferable than the urethane IMHO. The urethane just adds friction fore/aft and bind bump/droop. Neither is good.

I'm pretty confident the reason for Gm having worse rear end reliability than the Fords is all due to axle hop and no diff cover is going to fix that. I've never blown a rear end, and only rebuilt...

For clarity, you don’t have to add a drain plug to the cover, you can add it to the housing. The GMs have a nice cavity right at the bottom that is perfect for this.
