Level/Fill plug Salisbury diff

[Bas]

Hi!

Was planning to do a diff oil change over the weekend, but ran into the following plug on my Salisbury diff:
170392
Has anybody seen one of these before? Can I just safely put some pliers to work to get it off or is there a special socket for these?

An open ender of the correct size, or, dare I say it, a correctly fitted shifter.

You'll just butcher it with pliers/multigrips

theres as special socket for it, but most use an open ender

Thanks!

I'll give an open ender a go!
