70 dart 470 ci drag car build.

My Dana in my black duster almost has a constant leak till I tapped the axle and screwed a vent in it that I got from Summit. What an easy fix to a constant issue.
The location of my vent is weird it's butted up against the housing instead of just on the tube.
I will weld a bung or nut on where I put it and install the vent.
