Duke, did a slave recently on W124 (LH drive). Hydraulic line was removed from below with a crowfoot. Just had enough space for the extension (was still a little angled to the fitting). The 13mm bolts were attacked from behind the flex disc with a series of extensions. I found that bleeding was best done per the book, forcing fluid in to the slave cylinder, using the RF brake as a source (I don't have a pump). Of course, the brake and clutch bleeder screws are different diameters, so there was a bit of a mess. Hope this helps.
