<Snip> Andrew, As far as I'm aware the only difference in the boxes is the gear ratios otherwise they are the same. Later boxes can be considered to be "stronger" A disadvantage of later boxes is that the filler tube and dip stick disappeared along with the drain plug which makes changing the oil a pain in the arse. (Around about the time the "low nose" model change came in 1987 - 1988ish) The drive shafts do not bottom in the cups as they move in and out as the suspension moves. THe size of the cups did vary depending on the age of the car. The tended to be smaller on older boxes and thus the three bearing spider, inner joint, was smaller. I'm not exactly sure that the shaft length changed, although they were a different length on the 99, 99 combi etc. Somebody could of swapped all these parts about when changing the box. I have noticed that on my Saabs the shafts don't sit in the same place in the cups, but it hasn't caused any problems. It may be an engine mount thing as they get older. I'm not sure. The boot covers last forever which is good and bad because the grease can "dry out" over time. It's always worth backing off the giant hose clip, pulling back the boot and putting alittle moly grease in once a year or so. Hope this helps, Oophs went on a bit!! ;-) Malc Scotland Sent via Before you buy.
