Hoping someone can either confirm or deny in regards to the inside of these diffs now, the O ring set p/n 86016 the small red o ring in the set would these be the same ones just "a la carte" ?

Reason I am asking is because opening up the diffs on this one only had the larger (black one) in place but not the red so would like to see if I can source just what's needed to seal these up for diff oil application. Otherwise i'll just have to go with the o ring set option
