[Rovering]

Hello all,
Yes I am still alive, not returned from the dead!
I am moving from Hamilton, New Zealand to Perth, Western Australia in early Feb 2020.
Anyway, the issue I have is that my ZT190, which no one seems to want, I am now going to keep, as a back up car here in NZ, in case my Australia venture goes belly up!
The main radiator to motor hose, that has the bleed screw in it, is leaking slightly around the bleed screw (the screw head has crumbled/broken).
I am trying to locate a new replacement hose.
Have had a look on the Rimmer’s website, but can’t seem to find it, under MG or Rover.
Does anyone have a part number or link to where I can get one please.
Many thanks,
Graeme Larsen
