Went online car-hunting after a few shandies, and ended up with this:
The missus is not happy! A lovely Mk1 180, £650. Happy days.
Needs a set of clutch hydraulics (thanks Dark Ice Designs, need to fit it now!) and a few cosmetic imperfections sorting - apart from that, it's bang on.
Need to get rid of the silly cone filter, and decat it next.
