Don't know about the use of alloy yokes - I know was half asleep when I whanged the bolt back in . . . and crack . . . I thought alloy / steel might simply have been an age / cost cutting thing - or they too broke a few. But I suppose it could be a hint of weight saving against the extra weight of the ZF bits.
As for other Alfa inboard discs - I disliked the adjusters on the back of the 75 . . . I've not seen a Sud for years. Sold some Lancia wheels to a guy with one a few years ago - but thinking about it, probably close to 20 yrs ago.
