Also thought I'd record my findings on the much maligned cable style window regulators. After opening my old ones up I quickly retreated and bought two new ones from Alfa Service. These are handed, so be sure you use the right one on the right side.
The primary trouble with installing them is not the routing, or even access for hands, its the fact that the wires don't want to wind nicely on the spools and have lumpy parts to them from how they were shipped. There are a few recommendations on the BB to clamp the unit in a vice and straighten things out but I found bolting it to the door and spooling it over 3 of the 4 pulleys to be easier. I did that, attached the door handle (NB: check that your old door handles don't have their splines all gnarled. Mine were. Bought new). and ran the thing back and forth until I was happy, adding PTFE dry lube as I did. When it was reasonably tidy I unbolted it entirely and pushed it 'into' the door so that the splines on the winder attachment were almost inside the door. This is the only way I found its possible to hook the wire over the 4th pulley. I always found it easiest to use the lowest, rearmost pulley as the last one. Then with it seated on all pulleys, I reinserted its 3 studs and bolted it up. The washers I used aren't quite large enough - I need to replace them. I have the factory hardware on the other side - there is a conincal lock washer, m5 nut and very large washer. Then, I loosened the bolts and rotated the whole unit to put tension on the cable.
I've yet to attache the glass and can't quite figure out... can you get the glass with its alum blocks into the door or do the blocks go on the SS cables, then the glass into the blocks?
