The wiper system from a Saab 900 is basically a Lucas type with the worm gear type cable running in a 5/16 steel brake line and the transmissions clamped on flairs put where you like. The beauty for those of us in the states is that Saab uses a knurl that is large enough to use standard US size wiper arms and they have much larger sweep. (As opposed to the little bitty knuls and the approx. 90 degree sweep they use on the UK cars.) Now there is a company in Georgia that is making functionally equivalent new units.
I know this is a little off subject, but someone trying to figure out a wiper system might look here for a clue. The contact info for the Georgia outfit is in a previous post.
