Delta 4wd and Integrale were \I believe the only Lancia 4x4s officially imported. I think there were 4x4 versions of various post Delta cars sold in Europe.
I have seen Graham's car which is very straight and in nice condition. The wheels are Beta and I would remove them in an instant. I am pretty sure they have the wrong offset and they just don't look right. The original wheels suite it perfectly or failing that some Dedra or Y10 alloys would do.
