Welcome Andy!
Hypothetically I'd say ****!! Not a very common car to be fetching stuff for. My best suggestion would be keep a look out for one being broken. As far as ancillary parts I'm not 100% sure on commonality.
The contact is away all this week so are you ok to hold fire till next week? I can't see it being a problem as did exactly same for first Japshow, I'd just want to be 100%.
Welcome!
Looks like a great example . Not sure of the local meets in Wales I'm afraid but do check the meets section. The club is present at some large Jap meets like Japshow, Japfest etc.
