I thought that it was 1/4 inch pipe thread... ?:? Call WH tomorrow and ask Mark Beck what the thread is, they do sell replacement vents.

The front D44 is 7/16-20, not sure about the rear.

The Bronco Guru's have spoken, passing the knowledge on to those of us who aspire to be Guru's ;D

Sorry, guess I have been a work too long...

Mine broke off also so I tapped it with a 1/4" NPT tap and used hose adaptor fitting.
For the brakeline end, I just welded a 7/16" bolt (bolt head first) to the axle housing and used a nylock type nut to hold it in place.
