8 3/4 axle vent bolt
If you have a 7 1/4 there is no dedicated vent bolt. Just a standard bolt to hold the brake Y adapter in place. as stated above there is a welded on cover that is the vent.
Green is the unvented brake Y adapter hold down bolt
Red is the vent.
It might be under decades of grease and dirt.
If it's 8 3/4 the vent bolt also holds the brake Y adapter in place.
Post a photo of your rear end. ( keep it clean boys)
