Hi Wrenched, did you buy your SA car in Dorset, owned by a guy in Bath, Flavia 2000 coupe 1970 in Rosso York [maroon]? I looked at it before buying an exact replica via Richard Thorne. Mine was more messed with, ran less well, was more expensive and needed re-bushing throughout. Ah well. Still I love it.
You can get ARB bushes at good price from Colin Clamp of the Lancia Flavia Consortium. You may need to join the consortium first, you get access to lots of info and newsletters etc.
