Van Diemen RF80/VD80 - Details

[ExcelR8]

I've just bought myself a big Meccano set (or thats what the wife is calling it). It's actually a RF80/VD80 Van Diemen.
I last owned one back in 1989 and have been 'out' of racing for some time - I think I'm having a mid life crisis and have decided to try to do some racing again.
I think I can remember most about putting it together (I'm no expert, but do just about know one end of a spanner from the other) but if anyone has any details they can share with me (setup sheets, parts list, bolt sizes, pictures to assist with the build, etc.) I'd really appreciate any assistance, as there are some parts missing!
I'm also after a Mk9 gearbox if anyone has one, or knows where one is??
Actually, I'm after some spares as well (there were none with it) so if there are any out there, for the right price, I'd be very interested.
Thanks,
Tim
