While disassembling the Dana 44 I picked up off of CL, I noticed that the vent tube and fitting were missing. Wondering what the fitting size is? Tried a few brass fittings I had and did not want to force it. Assume it is NPT. Looked on line and one of the Mopar parts places wants $40 for the kit. Figured I would make my own and pickup a check valve for the top for $5.
