GT500 Rear Diff Cover - Vent fitting size / thread

[KBBOSS1086]

Does anyone know the size and thread type of the vent port on the GT500 Diff Cover? I recently purchased one and would like to install a vent tube but haven't been able to verify the proper fitting size / thread.

Thanks,
Sean

Sean try a 7/16"-20 bolt, I think that is the pitch. I think a -4 fitting may fit.

7/16" - 20 IIRC too. I think
I found some kind of flare fitting that worked.

Thanks guys. I will give them a shot and report back with the results.
