Thread: front axle breather help needed

Hi guys,
I have just swapped out my front diff housings as other was damaged. My prob is on the old housing diff breather had banjo bolt on the new it had a brass collar. I assume it was for a push in connector similar to air line fittings as that is what it looked like. Upon investigating i popped the collar out with hammer and chisel. Where can you buy the connectors ect. The hole in diff after taking out collar is 11mm which seems larger than banjo as was going to just tap hole for banjo but as always nothing is simple.
Any help is appreciated.

you can get the fittings from pirtek, but ide tap the hole to suit a BSP fitting, like the early diffs had.
the new diff have push in air line fittings, on my 90 the come out often

cheers phil
