I was just looking at my spare tranmissions the covers on the diff. have a breather tube on them but the one out of my 70 does not. my 70 is a OM code for the gt the others are OJ code 69 70 and 72. should i use the one without the vent or take one off the spares with the vent?

I have the same situation and am presently using the unvented one until I can get one of these:
