    I don't remember the size but here's a photo of mine. @steveespo might know.

    The axle and cover breather hole threads are 7/16"-20, which I think is also -4AN. I had to source my fittings through jegs and summit racing, couldn't find anything locally.

    3/8" seems large. If I remember correctly, the tube is 1/4".

    Haha. Seems to be some disagreement on what fitting is used in the axle tubes.

    Does anyone know what fitting they actually used in the axle tube?

    I used a 7/16-20 (-4AN) fitting on the axle tube. 1/4" is probably close enough to work. Do a google search and you'll find some threads about this.

    I ordered an allstar single bung breather/catch can. Im going to stop at the local offroad shop to pickup all the -AN fittings i need to complete the setup. I still have plenty of -10 Hose from my engine oil catch can install.

    installed my rear diff cooler setup today. Pieced it together and will run it this Monday/Tuesday at an event. A couple pics below, including the toggle switches I wired in to control from the drivers seat. One is for the diff cooler setup, the other is for my Accusump so I can pressurize oil right before I start the car and turn the system off after a session

    Question for others - how much additional fluid did you add as a result of the tubing, pump, and radiator volume? I estimated about 3/4 of a quart (measured tubing, but did not test volume of radiator or pump...).

    When I did mine I couldn't find anything that fit the axle tube so I drilled out the stock breather, and machined a hose barb from some stainless steel bar stock and welded it to the stock gutted breather. Then I ran a 3/8" hose up to this tank that I made and I just let the fluid fill and then drain back as the car cools off so I don't lose any fluid.
    Its been trouble free.

    I confirmed that a -4AN 45° fitting works perfectly in the top of the diff cover, i could not get it to thread into the axle tube though.

    I need to buy a -4AN push lock hose and some different fittings this week. Then i will post a parts list of everything i used so people of the future can easily get what works for them.

    The biggest problem i have found is that nobody has posted part numbers and specific info for others.

    That's why I had to make mine from scratch...who knew?
