GTA Right hand door stay

Hi Alpiners
Does anybody have or know where I can get one of these?
The lever with the pin at one end and the kinks that slips between the rollers in mine has broken
The restoraton of my blue 90 Atmo is vitrually complete apart from this - total respray, looks great, with final reassembly (door etc are back on, down to installing glass, fitting decals and fitting some trim) almost complete.
I would appreciate any help.
I live in NZ but have a UK address parts can be sent to for me.

Cheers (and living in hope!)

Graeme

looking forward to some pictures too.

Cheers Simon
Pictures of both cars to come.
The black '86 with the engine job, 4-barrel Quickfuel, heads on heavily modified inlet manifold with ram, cams etc is going really well.
Just some interior tidying to do now.
Regards
Graeme
