8.75 drain plug

my rear end rebuilder told me that i need to change the oil in it after abiut 159 miles. of course, i thought to ask this AFTER i reassembled the unit.....

so i was rereading the mopar action article on drilling and tapping a pipe plug into the bottom of the housing. this just seems like its begging for leaks and troble. am i wrong> is there a better solution that desnt require me pulling it all apart again? or am i just being paranoid?

let me know what you guys think/have experienced.
