I am wondering how to go about adding a drain plug and fill plug to rear diff cover. Those of you that have done so, please send some pics and some parts you completed the project with. How you cut the hole, what size did you go with, etc. I noticed 565bbchevy made a comment that he did such upgrade.... I am not even going to attempt to loosen the drain bolt on the housing I have. It is a torx (6 sided) plug and it's somewhere in size between a T50 and T55. Thanks!
