These aluminum plugs thread into the poppet ball holes in the front bearing cap on 1972-1979 Dana 20 Transfer Cases.  I've yet to find a rebuild kit that includes this plug.  If your case has the plastic plugs, these will replace them.

Auction is for 2 plugs and includes oil resistant Buna-N square profile o-rings (similar to the original) to ensure a good seal.

These also fit the Dana 300 transfer case, but generally only one is needed, as the other opening is where the 4wd indicator switch installs.  See my other auctions for a single plug.

I ship all parts in one day, and often the same day if the order is received soon enough.  If you see a longer ship time listed, I am out on a Jeeping trip and will mail your item(s) as soon as I get home. 

I buy and sell on ebay to support my Jeep habit!  Check my feedback and bid with confidence.  Please check out my other auctions!
