Not sure what exactly it is called or if it has a part # but the plastic surround (Gray), the bit which is behind the lever which opens the doors from inside (and which has a screw on it) is broken at the screw itself for the LHS door.

Where to get it from for a TF Sports.

Wreckers? Mits?

I'm in Sydney and willing to pick it up if a member has a spare one and is close by

I got one, brand new from Mitsi for about $16

its called an escutcheon or something like that.
