I'm sharing this fix, in case others find themselves in a similar situation:

The stock TJ/LJ Dana 30 vent tube fitting, part # 83504653 (Supersession(s): 83500330) is no longer available. As most know, this fitting goes into the top left portion of the TJ/LJ Dana 30 and is where the vent tube attaches. It's a common problem that this plastic, press-in fit, part breaks easily when removing the vent tube. Or, in my case, they're sometimes missing, when a used Dana 30 assembly is purchased. Since the Dana 30 I bought was missing the part, I spent hours looking for a solution, ending up with the most common fix being to use a 1/8 NPT tap and screw in brass fitting.

I only wanted to use the tap as a last resort, not having found other viable options, so I took a $3.99 leap of faith. I ordered the JK Mopar Axle Vent, Part # 68017179AA-M, and, after measuring it, discovered that it would indeed fit. The new replacement part is metal, which is a big bonus over the stock plastic part it replaced. Although the new part was a very tight interference fit, the install was straight forward, with a couple simple tricks. The steps were basically this:

1. Inspect the hole in the housing to ensure no plastic stock parts are still there. If so, you'll have to remove them before proceeding.
2. Once the opening is clear of the stock part, I gently used a round file to clean out any debris
3. I then used a Q-tip soaked in WD40 to clean the opening.
4. With that done, I used another Q-tip to apply a coat of Jet-Lube 550 anti-seize around the inside of the opening that the new part would go in
5. I then placed a 10mm deep well impact socket over the end of the replacement part, where the vent hose attaches
6. Lining the new part up with the hole in the housing, I gently drove the fitting in with a small hammer, being careful to keep it square
7. When the new fitting was in, I attached the vent tube and declared victory!
