Difference between left handed and right handed trem bar?

[JamesA1902]

So I recently acquired a lefty PRS SE and was just wondering if I'd need to buy a left handed trem bar as some that I've seen state that they're for only right handed models. I haven't used a tremolo bar before even though I've been playing the guitar for 14 years, for some reason I've just never thought to get one until now. If I do need to get one specifically for a lefty does anyone have any ideas where I can get one from as previously stated I haven't managed to find one so far.

Cheers,
James \m/
